- Deformation of the soccer ball 106 is more significant and visually apparent—a surface of the soccer ball 106 typically becomes indented or flattened in response to a sufficiently swift kick.
- the strike zone 140 shown in FIG. 16 represents an area of the surface of the soccer ball 106 where contact with a portion of the individual's 10 foot 12 and/or deformation of the soccer ball 106 may occur during a kick.
- the point of impact 150 shown in FIG. 16 occurs within the bounds of the strike zone 140 , and represents the location on the surface of the soccer ball 106 that approximately coincides with the center of the area of the foot 12 in contact with the soccer ball 106 .
- the point of impact 150 is in alignment with an exterior marking 202 of the soccer ball 106 , as first described in connection with FIG. 5 .
- Corresponding markings are illustrated on the foot 12 (encased in a soccer boot) in FIG. 16 to show an exemplary position on the foot 12 where the foot 12 may impact the soccer ball 106 .
- Embodiments of the present invention provide an analytical framework for analyzing motion characteristics of sport balls 106 , such as a soccer ball 106 , including analyzing the relationship between the location of the point of impact 150 between an individual's 10 foot 12 and a soccer ball 106 and motion characteristics of the soccer ball 106 during and after it is kicked.
- Examined motion characteristics include ball speed, ball spin rate, ball spin axis, and ball launch angle.
- FIG. 17 provide a useful diagram for characterizing the locations of points of impact 150 on the surface of a soccer ball 106 .
- a soccer ball 106 viewed from the front has been divided into four quadrants: I, II, III, and IV.
- a first point of impact 150 , a second point of impact 152 , and a third point of impact 154 are also illustrated.
- the precise location of the point of impact 150 , 152 , or 154 between an individual's 10 foot 12 and a soccer ball 106 is correlated to motion characteristics of the ball 106 including ball speed, ball spin rate, ball spin axis, and ball launch angle.
- the soccer ball 106 is kicked straight on such that the point of impact corresponds to point 150 in FIG. 17 —i.e. aligned with the dead center of the soccer ball 106 where quadrants I, II, III, and IV meet—substantially all of the energy from the foot-ball impact will transmitted as a linear displacement.
- the soccer ball 106 will be launched at a relatively high speed with little or no spin, a relatively level spin axis, and a relatively flat launch angle.
- the soccer ball 106 is kicked far off to one of its sides relative the individual's 10 approach and the intended flight path such that the point of impact corresponds to point 152 in FIG. 17 —e.g. aligned with the “equator” of soccer ball 106 but off to the side in the direction of quadrants I and IV—substantially all of the energy that is transmitted will impart spin on the soccer ball 106 .
- the soccer ball 106 will be launched at a relatively low speed with relatively high spin, and still with a relatively level spin axis and a relatively flat launch angle.
- the soccer ball 106 may be launched at a relatively moderate speed with relatively moderate spin, but this time with a tilted spin axis and a relatively higher launch angle.
- a quadrant grid similar to the one depicted in FIG. 17 could be drawn onto the surface of soccer balls 106 and oriented toward the intended flight path of the soccer ball 106 , and a visual identifying substance such as a food-grade dye can be applied to individuals' 10 feet 12 (or footwear).
- a visual identifying substance such as a food-grade dye can be applied to individuals' 10 feet 12 (or footwear).
- the locations of strike zones 140 and points of impact 150 for soccer balls 106 kicked by individuals 10 can be identified based on the locations of dye markings on the soccer balls 106 with respect to the applied grids.
- measurements can be taken during the kicks to identify motion characteristics of interest such as ball speed, ball spin rate, ball spin axis, and ball launch angle.
- a substance such as a rapidly evaporating alcohol can be applied to individuals' 10 feet 12 (or footwear), and monitored kicks can be recorded with an infrared camera.
- the locations of strike zones 140 and points of impact 150 for the soccer balls 106 kicked by individuals 10 can be identified based on an analysis of the recorded images of the locations of evaporating alcohol on the soccer ball 106 , as sensed by local changes in temperature caused by the evaporation.
- Regression analysis is a statistical process for estimating the relationships among variables. Regression analysis can be used to fit a predictive model to an observed data set of values. After developing such a model, if additional values of one or more variables (e.g. ball speed, ball spin rate, ball spin axis, ball launch angle, or point of impact 150 ) can be determined, the fitted model can be used to make a prediction of the values of unknown variables. When building a suitable model, given variables that may be related, regression analysis can be applied to, for example, quantify the strength of the relationships between the various variables, to assess which variables may have no relationship at all, or to identify which subsets of the variables contain redundant information.
- variables e.g. ball speed, ball spin rate, ball spin axis, ball launch angle, or point of impact 150
- a linear regression analysis can be employed to predict the relationship between ball speed, ball spin rate, ball spin axis, ball launch angle, or point of impact 150 .
- data are modeled using linear predictor functions, and unknown model parameters are estimated from the data.
- Exemplary results of a linear regression analysis correlating points of impact obtained empirically to points of impact determine from applying a linear regression function to sensor module 102 data are illustrate in FIG. 18 .
- the regression analysis can alternatively rely on a tool known as a regression tree.
- a regression tree is a predictive model that maps observations about an item to conclusions about the item's target value. The goal is to create a model that predicts the value of a target variable based on several input variables.
- a tree can be derived by splitting the source set into subsets based on an attribute value test. This process is repeated on each derived subset in a recursive manner called recursive partitioning. The recursion is completed when the subset at a node has all the same value of the target variable, or when splitting no longer adds value to the predictions.
- each x(n) variable represents one of the soccer ball 106 motion variables, while the leafs of the regression tree represent an outcome variable after applying the regression conditions for a given branch.
- a regression analysis results in a model that establishes a relationship between ball speed, ball spin rate, ball spin axis, ball launch angle, and point of impact 150
- measured or calculated values of some variables can be used to determine others that are unknown.
- data from a sensor module 102 of a soccer ball 106 may be used to determine ball speed, ball spin rate, ball spin axis, and ball launch angle, for a given kick, and this data may be used to determine a point of impact 150 for the kick.
- a regression analysis can be used to determine a point of impact 150 for a kick based on acceleration data obtained for a sport ball 106 , such as a soccer ball 106 .
- the acceleration data may be obtained from a sensor module 102 of the sport ball 106 , or from another source.
- the regression analysis can be used to determine a point of impact 150 for a kick based on other data such as magnetometer data, angular momentum sensor data, or multiple types of data.
- a regression analysis process 460 begins at step 462 by receiving acceleration data.
- the regression analysis determines soccer ball 106 speed.
- the regression analysis determines soccer ball 106 spin rate.
- the regression analysis determines soccer ball 106 spin axis.
- the regression analysis determines soccer ball 106 launch angle.
- the regression analysis determines the location of a point of impact 150 on the soccer ball 106 .
- the regression analysis may rely on a regression tree.
- a regression tree may be used when linear regression techniques do not yield suitable predictive results.
- the regression tree is a model that can predict the value of a point of impact 150 based on ball speed, ball spin rate, ball spin axis, and ball launch angle derived, in one embodiment, from acceleration data.
- the regression tree can provide local data correlations that are not valid globally.
- the key is fitting a given set of input data into a particular portion of the regression tree where a good fit among the data can be found. For example, one branch of the regression tree may be a good fit for a kick with a high spin, low speed kick, while another branch of the regression tree may be a good fit for a kick with a low spin and high speed. Additional variables can be added to the analysis in various branches of the tree. But at some point, adding new variables requires significantly more data analysis while giving little added accuracy. In other words, at some point continuing to split new branches of the tree no longer adds value to the predictions.
- the best method for determining soccer ball 106 speed may depend on whether an underlying variable is above a given threshold.
- a speed determination process 480 begins at step 482 (which may correspond to step 464 of FIG. 20 ) when speed is to be determined.
- a determination is made as to whether the spin rate of the soccer ball 106 is above a certain threshold.
- other variable thresholds may be employed.
- a threshold of five revolutions per second may be used.
- Kicks where the soccer ball 106 is determined to be rotating less than five revolutions per second may be deemed “slow spin” kicks, while kicks where the soccer ball 106 is determined to be rotating more than five revolutions per second may be deemed “high spin” kicks.
- the regression analysis may proceed by analyzing the peak-to-peak acceleration output from an acceleration sensor, such as sensor module 102 .
- the peak-to-peak acceleration may consist of difference between the highest and lowest acceleration readings of resultant acceleration values.
- the resultant acceleration values could factor in readings from each axis of the accelerometer.
- the regression analysis may proceed by calculating root mean squares of the peak-to-peak acceleration.
- a root mean square of a value is a scalar measure of the magnitude of a varying quantity of the value. Root mean squares of the peak-to-peak acceleration values may be calculated for low-spin kicks because acceleration output behaves linearly under such conditions.
- the regression analysis analyzes both the root mean squares of the peak-to-peak acceleration values and spin data itself to determine soccer ball 106 speed. Factoring in spin data corrects for some of the uncertainty in the speed calculations introduced by virtue of having to apply root mean squares of the peak-to-peak acceleration values.
- the outcome of speed process 480 can be fed into a general regression analysis as specified in regression process 460 of FIG. 20 in order to determine a point of impact 150 for a kick.
- the soccer ball 106 must be in a free flight state after being kicked in order for the sensor module 102 to provide accurate data for soccer ball 106 motion characteristic determinations.
- the motion monitoring system 100 is able to make accurate data for soccer ball 106 motion characteristic determinations even when the soccer ball 106 in not in a free flight state after being kicked.
- One non-free flight state after a soccer ball 106 is kicked is known as a “grounder,” which occurs when the soccer ball 106 is kicked and rolls or repeatedly bounces across the ground.
- Another non-free flight state after a soccer ball 106 is kicked is known as a “toe scoop,” which occurs when the soccer ball 106 is not truly kicked but actually scooped relatively slowly by the foot 12 and then released; the soccer ball 106 is not truly impacted, just scooped—in a non-free fall state—and tossed.
- the motion monitoring system 100 when the motion monitoring system 100 determines that a grounder or toe-scoop has occurred, the individual 10 will be given a general error message. In another embodiment, the motion monitoring system 100 will specifically inform that the individual 10 that a grounder or a toe-scoop has been kicked. A more specific error message may prevent the individual 10 from losing confidence in the system 100 if the individual 10 assumed that any general error resulted from malfunction of the device, and not the individual's 10 improper grounder kick.

- FIG. 24 is an exemplary GUI window that may be provided by the kick it module instructing the individual 10 to tap the ball icon 602 when they are ready to monitor a kick. If not previously selected, the individual 10 may activate a selection icon 604 for indicating which foot 12 (left or right) the individual 10 is going to be kicking a soccer ball 106 with.

- the soccer ball 106 may prepare for an upcoming kick by adjusting its power consumption, adapting its processing, begin data recording, calibrate its sensors, or other operation.
- the soccer ball 106 may send a return signal to the portable electronic device 306 to indicate that the soccer ball 106 is ready to be kicked.
- the individual 10 may kick the soccer ball 106 .
- a soccer kick can involve a series of complex motions by an individual 10 leading up to the striking of the soccer ball 106 by the individual's 10 foot 12 .
- the individual 10 may need to utilize a particular approach and ball-striking mechanics.
- the sensor module 102 When the soccer ball 106 is kicked, the sensor module 102 is capable of recording movement date associated with the kick, as described above with respect to FIGS. 8-21 .
- the soccer ball 106 having the sensor module 102 alone or in combination with the portable electronic processing device 306 , may be capable of determining motion characteristics of the soccer ball 106 including ball speed, ball spin rate, ball spin axis, and ball launch angle.
- the paired sport ball 106 may begin sampling data from the sensor module 102 at a predetermined rate. For example, in embodiments where the sensor module 102 includes one or more acceleration sensors 118 , the sport ball 106 may sample data from the acceleration sensors 118 at a rate of 1 kHz. In one embodiment, the sport ball 106 may continue sampling data from the acceleration sensors 118 at a rate of 1 kHz and saving the acceleration data into a file 700 on a memory device of the sport ball 106 indefinitely, until a predetermined amount of required memory is reached, or until all of the kick monitoring session is complete.
- the sport ball 106 may employ a data sampling system that relies on both a file 700 on a memory device and a separate buffer data structure, such as a circular buffer 702 of fixed size that is significantly smaller than the size of the file 700 on the memory device.
- the sport ball 106 in response to receiving the indication from the portable electronic device 306 that the individual 10 is ready to monitor a kick, the sport ball 106 may sample data from the acceleration sensors 118 at a rate such as 1 kHz and continually save the acceleration data into the circular buffer 702 , overwriting previous data as necessary, as shown in FIG. 50A .
- the sport ball 106 may employ a compression algorithm to optimize memory utilization and post kick data analysis.
- the sport ball periodically analyzes the sampled data in the circular buffer 702 to determine when to alter the rate at which samples are saved into memory based on the variability of the data. If the sport ball 106 determines that the data has a low variability, the sport ball 106 may periodically save low variability values into the file 700 on the memory device of the sport ball 106 at a rate as infrequent as 1 Hz, as shown in FIGS. 50A and 50B . This practice may allow the file 700 on the memory device to take up less memory space than if the sampled data were saved directly to the file 700 on the memory device of the sport ball 106 at a much higher rate such as 1 kHz. In FIGS.
- saved data 704 from the accelerometer is identified by reference numeral 704
- low variability values 706 e.g. a 1G acceleration due solely to gravity
- the compression algorithm can adjust the data save rate dynamically in a way that correlates with the signal variability.
- the sport ball 106 may begin saving the sampled data directly into the file 700 on the memory device of the sport ball 106 instead of to the circular buffer 702 , as shown in FIG. 50B .
- the sport ball 106 may also insert some or all of the data existing at that point in time in the circular buffer 702 into the file 700 just ahead of the new sampled data, as shown in FIG. 50C . In this way, the file 700 on the memory device is able to capture acceleration data at each point in time and only in the highest fidelity necessary at each moment in time for later post kick analysis.
- the portable electronic device 306 may communicate with the sport ball 106 to download saved data from the file 700 on the memory device of the sport ball 106 .
- the portable electronic device 306 may first seek to determine how much data is presently stored in the file 700 on the memory device of the sport ball 106 . In some embodiments, this sort of communication may occur periodically, such as once every 100 or 200 milliseconds.
- the communication to determine how much data is presently stored in the file 700 on the memory device may occur every 100 or 200 milliseconds until the portable electronic device 306 receives data indicating that the memory device has reached a certain level of capacity, such as being 2% full, 25% full, 50% full, or 100% full.
- the portable electronic device 306 may begin to download saved data from the file 700 on the memory device of the sport ball 106 . In this way, communications between the portable electronic device 306 and the sport ball 106 can be reduced to only the most essential communications, and data storage on the memory of the sport ball 106 can be managed.
- the sport ball 106 may broadcast the status of its memory capacity without prompting for such information by the portable electronic device 306 .
- the portable electronic device 306 may constantly download saved data from the file 700 on the memory device of the sport ball 106 .
- FIG. 25 is an exemplary GUI window that may be provided by the kick it module that provides a visual display to the individual 10 giving them feedback about the motion characteristics of the soccer ball 106 during their kick.
- the exemplary GUI includes a statistical display bar 606 that may provide, for example, information on the maximum speed of the soccer ball 106 during the post-kick flight or information on the maximum spin rate of the soccer ball 106 during the post-kick flight.
- the statistical display bar 606 may also provide an indication of which foot 12 the individual 10 kicked the soccer ball 106 with, as well as an indication of whether the individual 10 has designated the kick as a “favorite” kick.
- the exemplary GUI of FIG. 25 also includes a video element 610 .
- the exemplary video element 610 shown is an animation that represents the flight path of the kicked soccer ball 106 in three dimension, set upon the background of a representation of a soccer goal.
- the animation may start automatically, while in other embodiments the individual 10 must provide an input to the portable electronic device 306 to request that the video play.
- the perspective of the animated flight path may change such that the individual's 10 perspective may appear to rotate around the animated flight path to provide a better perspective on the flight path.
- the individual 10 may be presented with a selection icon 604 allowing the individual 10 to choose different animated views of the kick and fight path such as, for example, a downfield view, an angled view, or a side view.
- the particular flight path shown and animated may be based partially or entirely on the determined motion characteristics of the soccer ball 106 , such that the flight animated flight path is a realistic approximation of the actual flight path of the kicked soccer ball 106 .
- a swipe element 608 may indicate to the individual 10 that swiping their finger across the display screen may lead to other pages that display additional feedback.
- buttons, switches, links, or other elements may be substituted for a swipe element 608 .
- FIG. 26 is an exemplary GUI window that may be provided by the kick it module that provides one such other visual display—a ball strike display.
- the exemplary GUI window of FIG. 26 could be displayed to the individual 10 after the individual 10 swiped the display of the exemplary GUI window of FIG. 25 to transition from the display of flight path feedback to the display of FIG. 26 .
- FIG. 26 provides information on point of impact 150 data. Such data may be obtained, for example, according to a regression process 460 analysis as described above with respect to FIGS. 16-21 . As noted above, a relationship exists between the location of the point of impact 150 between an individual's 10 foot 12 and a soccer ball 106 and motion characteristics of the soccer ball 106 during and after it is kicked.
- the exemplary GUI display FIG. 26 illustrates a point of impact icon 612 overlaid on top of a ball icon 602 , where the point of impact icon 612 is representative of the calculated point of impact 150 derived from the regression process 460 analysis as described above with respect to FIGS. 16-21 .
- the point of impact icon 612 displayed via portable electronic device 306 corresponds to the calculated point of impact 150 that represents the location on the surface of the soccer ball 106 that approximately coincides with the center of the area of the foot 12 in contact with the soccer ball 106 .
- the methods previously described for analyzing the relationship between the location of the point of impact 150 between an individual's 10 foot 12 and a soccer ball 106 and motion characteristics of the soccer ball 106 during and after it is kicked can be used to generate feedback to the individual 10 via the portable electronic device 306 , such as visually illustrating the location of a point of impact icon 612 overlaid on top of a ball icon 602 , as shown in FIG. 26 .
- the point of impact icon 612 shown in FIG. 26 includes a circular dot with a series of animated rings that may visually “pulse” to help draw attention to the location of the point of impact icon 612 .
- This particular point of impact icon 612 appears below and to the right of the center of the soccer ball 106 , as viewed from a front perspective.
- the exemplary GUI window of FIG. 26 also includes the same statistical display bar 606 shown in FIG. 25 that provides information on the maximum speed of the soccer ball 106 during the post-kick flight, information on the maximum spin rate of the soccer ball 106 during the post-kick flight, an indication of which foot 12 the individual 10 kicked the soccer ball 106 with, as well as an indication of whether the individual 10 has designated the kick as a “favorite” kick.
- the exemplary GUI window of FIG. 26 additionally includes the same swipe element 608 shown in FIG. 25 that may indicate to the individual 10 that swiping their finger across the display screen may lead to other pages that display additional feedback. Again, other embodiments, buttons, switches, links, or other elements may be substituted for a swipe element 608 .
- the motion monitoring system 100 application running on the portable electronic device 306 may log and display multiple point of impact icons 612 corresponding to multiple points of impact 150 between an individual's 10 foot 12 and a soccer ball 106 during multiple kicks. Such a display is illustrated in FIG. 27 .
- the displayed kicks may be consecutive kicks from a single session, or may be from other periods of time.
- the ball strike display may be limited to generating a display corresponding to a certain number of most recent points of impact 150 , such as the last five points of impact 150 , or the last ten points of impact 150 .
- multiple point of impact icons 612 corresponding to each point of impact 150 are displayed as a heatmap overlay over a single ball icon 602 .

Abstract
Description
- The present application is a divisional of U.S. patent application Ser. No. 15/848,296, filed Dec. 20, 2017, which is continuation of U.S. patent application Ser. No. 14/120,272, filed May 14, 2014, each of which are incorporated herein by reference in their entirety.
- Embodiments of the present invention generally relate to methods and systems for monitoring the motion of a piece of athletic equipment during an athletic activity. More particularly, embodiments of the present invention relate to methods and systems for monitoring the motion of a sport ball used by an individual during an athletic activity.
- Athletic activity is important to maintaining a healthy lifestyle and is a source of entertainment for many people. Some individuals prefer to engage in team athletic activities such as, for example, soccer or basketball, while other individuals prefer to engage in individual athletic activities such as, for example, running or skiing. Regardless of whether the activity is a team or individual activity, it is common for individuals to participate in both competitive sessions, such as a soccer match or a running race, and more informal training sessions such as conducting soccer drills or running interval sprints.
- Technology has resulted in the development of athletic monitoring devices that are capable of recording information about an individual's performance during an athletic activity using sensors, and in some cases providing feedback about the individual's performance. Some portable athletic monitoring devices employ sensors attached to a piece of athletic equipment. Such sensors may be capable of measuring various parameters associated with the individual's physical activity, such as motion parameters.
- Many existing athletic equipment monitoring devices are not portable and thus are not suitable for monitoring in many real world competitive or training sessions. Even those that are portable are often too heavy or lack sufficient battery and/or processing power to be used for extended periods under rigorous competitive or training conditions. In addition, while some existing athletic equipment monitoring devices are capable of making relatively simple motion or other performance determinations, more advanced determinations are often not possible or suffer from accuracy issues. Finally, the performance feedback provided by existing devices to individuals often fails to provide these individuals with quick, accurate, insightful information that would enable them to easily compare past performances, develop strategies for improving future performances, visualize performances, or select new training regimens or athletic equipment.
- What is needed are new athletic equipment monitoring methods and systems having improved capabilities, thus offering individuals engaged in athletic activities better tools to assess their activities. At least some of the embodiments of the present invention satisfy the above needs and provide further related advantages as will be made apparent by the description that follows.
- Embodiments of the present invention relate to a method for monitoring the motion of a sport ball that has been impacted by an individual during the course of an athletic activity includes the steps of a portable electronic device wirelessly receiving motion data from the sport ball, and the portable electronic device determining a point of impact based on the motion data, wherein the point of impact includes the location on a surface of the sport ball where the impact occurred.
- Embodiments of the present invention also relate to a computer program product including a non-transitory computer readable medium having computer program logic recorded thereon, for use in monitoring the motion of a sport ball that has been impacted by an individual during the course of an athletic activity, that, when executed by one or more processors of a portable electronic device, is capable of causing the portable electronic device to wirelessly receive motion data from the sport ball, and determine a point of impact based on the motion data, wherein the point of impact includes the location on a surface of the sport ball where the impact occurred.
- Additional features of embodiments of the invention will be set forth in the description that follows, and in part will be apparent from the description, or may be learned by practice of the invention. Both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.

sensor module 102 may communicate with other components of themotion monitoring system 100 via wired or wireless technologies. Communication between thesensor module 102 and other components of themotion monitoring system 100 may be desirable for a variety of reasons. For example, to the extent that thesensor module 102 records and stores athletic activity information, it may be useful to transmit this information to another electronic device for additional data processing, data visualization, sharing with others, comparison to previously recorded athletic activity information, or a variety of other purposes. As a further example, to the extent that thesensor module 102 has insufficient processing power, wide area network transmission capabilities, sensor capabilities, or other capabilities, these capabilities can be provided by other components of themotion monitoring system 100. With this in mind, possible communications means are described briefly below. - Wired communication between the
sensor module 102 and apersonal computer 304 may be achieved, for example, by placing thesensor module 102—or a piece ofathletic equipment 104 including thesensor module 102—in a docking unit that is attached to thepersonal computer 304 using a communications wire plugged into a communications port of thepersonal computer 304. In another embodiment, wired communication between thesensor module 102 and thepersonal computer 304 may be achieved, for example, by connecting a cable between thesensor module 102—or a piece ofathletic equipment 104 including thesensor module 102—and thecomputer 304. Thedata port 132 of thesensor module 102 and a communications port of thecomputer 304 may include USB ports. The cable connecting thesensor module 102 and thecomputer 304 may be a USB cable with suitable USB plugs including, but not limited to, USB-A or USB-B regular, mini, or micro plugs, or other suitable cable such as, for example, a FireWire, Ethernet or Thunderbolt cable. As previously explained above, in some embodiments, such cables could be used to facilitate power transfer to apower source 112 of thesensor module 102, in order to charge thepower source 112. Alternatively, thepower source 112 may be recharged by inductive charging, or by using a docking station with a chargingbase 200. - Wired connection to a
personal computer 304 may be useful, for example, to upload athletic activity information from thesensor module 102 to thepersonal computer 304, or to download application software updates or settings from thepersonal computer 304 to thesensor module 102. - Wireless communication between the
sensor module 102—or a piece ofathletic equipment 104 including thesensor module 102—and thepersonal computer 304 may be achieved, for example, by way of a wireless wide area network (such as, for example, the Internet), a wireless local area network, or a wireless personal area network. As is well known to those skilled in the art, there are a number of known standard and proprietary protocols that are suitable for implementing wireless area networks (e.g., TCP/IP, IEEE 802.16, Bluetooth, Bluetooth low energy, ANT, ANT+ by Dynastream Innovations, or BlueRobin). Accordingly, embodiments of the present invention are not limited to using any particular protocol to communicate between thesensor module 102 and the various elements of themotion monitoring system 100 of the present invention. - In one embodiment, the
sensor module 102—or a piece ofathletic equipment 104 including thesensor module 102—may communicate with a wireless wide area network communications system such as that employed by mobile telephones. For example, a wireless wide area network communication system may include a plurality of geographically distributed communication towers and base station systems. - Communication towers may include one or more antennae supporting long-range two-way radio frequency communication wireless devices, such as
sensor module 102. The radio frequency communication between antennae and thesensor module 102 may utilize radio frequency signals conforming to any known or future developed wireless protocol, for example, CDMA, GSM, EDGE, 3G, 4G, IEEE 802.x (e.g., IEEE 802.16 (WiMAX)), etc. The information transmitted over-the-air by the base station systems and the cellular communication towers to thesensor module 102 may be further transmitted to or received from one or more additional circuit-switched or packet-switched communication networks, including, for example, the Internet. - As shown in
FIG. 7 , communication may also occur between thesensor module 102, apersonal computer 304, and/or aremote server 302 via anetwork 300. In an embodiment, thenetwork 300 is the Internet. The Internet is a worldwide collection of servers, routers, switches and transmission lines that employ the Internet Protocol (TCP/IP) to communicate data. Thenetwork 300 may also be employed for communication between any two or more of thesensor module 102, thepersonal computer 304, theserver 302, and a docking unit. In an embodiment of the present invention, information is directly communicated between thesensor module 102 and theserver 302 via thenetwork 300, thus bypassing thepersonal computer 304. - A variety of information may be communicated between any of the
sensor module 102, thepersonal computer 304, thenetwork 300, theserver 302, or other electronic components such as, for example, anothersensor module 102, a mobile phone, a tablet computer, or other portable electronic devices. Such information may include, for example, performance parameter data, device settings (includingsensor module 102 settings), software, and firmware. - Communication among the various elements of the present invention may occur after the athletic activity has been completed or in real-time during the athletic activity. In addition, the interaction between, for example, the
sensor module 102 and thepersonal computer 304, and the interaction between thepersonal computer 304 and theserver 302 may occur at different times. - In some embodiments of the present invention, an individual 10 using the
motion monitoring system 100 may participate in the activity with thesensor module 102 physically coupled to a piece ofathletic equipment 104, but with no other portable electronic devices making up part of themotion monitoring system 100 in the individual's 10 immediate vicinity. In such an embodiment, thesensor module 102 would monitor the athletic activity using its sensors. Thesensor module 102 may also perform calculations necessary to monitor changes in the spatial orientation of the piece ofathletic equipment 104, or perform calculations necessary to determine a correlation betweenequipment 104 movement data and an activity metric. - Alternatively, in this scenario, other components of the
motion monitoring system 100 that are remotely located from the individual 10 during the activity could be relied upon to perform calculations necessary to monitor changes in the spatial orientation of the piece ofathletic equipment 104, or perform calculations necessary to determine a correlation betweenequipment 104 movement data and an activity metric. This could occur, for example after wireless transmission of athletic performance information directly from thesensor module 102 to apersonal computer 304 or aserver 302 during or after the activity, or after a wired transmission of athletic performance information directly from thesensor module 102 to apersonal computer 304 after the activity. - However, in other embodiments of the present invention, as illustrated in
FIG. 8 , thesensor module 102 may communicate with a portableelectronic device 306 of themotion monitoring system 100 that is also carried by the individual 10 during the athletic activity. In some embodiments, the portableelectronic device 306 may be carried by another person besides the individual 10, or not carried by any person. In some embodiments, the portableelectronic device 306 may be a watch, a mobile phone, a tablet computer, or other portable electronic device. In one embodiment of the present invention, as described in further detail below, in particular with respect toFIGS. 22-49 , thesensor module 102 may communicate with a portableelectronic device 306 running asport ball 106motion monitoring system 100 portableelectronic device 306 software application. - The portable
electronic device 306 may serve a variety of purposes including, for example, providing additional data processing, providing additional data storage, providing data visualization, providing additional sensor capabilities, relaying information to anetwork 300, or providing for the playback of music or videos. - In one embodiment of the present invention, the portable
electronic device 306 may be a dedicated portableelectronic device 306. The term “dedicated portable electronic device” indicates that the portableelectronic device 306 is not capable of serving another purpose outside of themotion monitoring system 100 of the present invention. For example, a mobile phone, a personal digital assistant, or a digital music file player (e.g., an MP3 player) may not be considered to be “dedicated portable electronic monitoring devices” as the term is used herein. In this manner, the dedicated portableelectronic monitoring device 306 may in some embodiments provide a simpler and/or more efficient device. - The portable
electronic device 306 illustrated inFIG. 8 is not a dedicated portable electronic monitoring device; the portableelectronic device 306 illustrated inFIG. 8 is a mobile phone. In alternate embodiments, it may be possible for thesensor module 102 itself to be embodied by a mobile phone. Including a portableelectronic device 306 in themotion monitoring system 100, such as a mobile phone, may be desirable as mobile phones are commonly carried byindividuals 10, even when engaging in athletic activities, and they are capable of providing significant additional computing and communication power at no additional cost to the individual 10. - In view of the above discussion, it is apparent that various processing steps or other calculations recited herein may be capable of being performed by various embodiments of the
motion monitoring system 100 disclosed herein, and are not necessarily limited to being performed by thesensor module 102, depending on the configuration of a particular embodiment of the present invention. For example, any of the processing steps or other calculations recited herein may be performed, in various embodiments, by thesensor module 102, by aserver computer 302, by apersonal computer 304, by a portableelectronic device 306, and/or any other network component, or by more than one component. - Embodiments of the present invention may involve the use of so-called “cloud computing.” Cloud computing may include the delivery of computing as a service rather than a product, whereby shared resources, software, and information are provided to computers and other devices as a utility over a network (typically the Internet). Cloud computing may entrust services (typically centralized) with an individual's 10 data, software and computation on a published application programming interface over a network. End users may access cloud-based applications through a web browser or a light weight desktop or mobile app while the business software and data are stored on servers at a remote location. Cloud application providers often strive to give the same or better service and performance than if the software programs were installed locally on end-user computers.
- Embodiments of the present invention may incorporate features of group athletic activity monitoring systems. Exemplary of group athletic activity monitoring systems are disclosed in commonly owned U.S. patent application Ser. No. 13/077,494, filed Mar. 31, 2011 (which published as U.S. Patent App. Pub. No. 2012/0254934), the entirety of which is incorporated herein by reference thereto.
- An overview of exemplary embodiments of components of the athletic equipment
motion monitoring system 100 of the present invention, includingexemplary sensor modules 102, has been provided above. - A description of various exemplary methods of using the
motion monitoring system 100 of the present invention to monitor changes in the spatial orientation or movement of a piece ofathletic equipment 104, or to determine a correlation betweenequipment 104 movement data and an activity metric is now provided below. - An individual 10 engaged in an athletic activity (or another interested person such as a coach, teammate, or spectator) may desire to obtain information about the motion of a piece of the individual's 10
athletic equipment 104 during the course of the athletic activity. - For example, if the individual 10 is participating in an activity that involves the use of a
sport ball 106, such as playing in a soccer match, it may be desirable, for example, to be able to determine the various launch angles at which the soccer ball 106 (i.e., football) was kicked by the individual's 10foot 12, to be able to determine the rate of rotation of thesoccer ball 106 after it was kicked by the individual 10, to be able to determine the peak speeds that thesoccer ball 106 was traveling at after being kicked by the individual 10, or to be able to determine the specific locations on the surface of thesoccer ball 106 where the individual's 10foot 12 struck the ball when kicking thesoccer ball 106. - By using the
motion monitoring system 100 including thesensor module 102 described above, embodiments of the present invention may advantageously enable the individual 10 (or their coach, teammate, or a spectator) to obtain this or other information about the motion of the piece ofathletic equipment 104 during or after the course of the athletic activity. - While various embodiments of the present invention are described in the context of the sports of soccer (i.e., football), the present invention is not so limited and may be applied in a variety of different sports or athletic activities including, for example, baseball, basketball, bowling, boxing, cricket, cycling, football (i.e., American football), golf, hockey, lacrosse, rowing, rugby, running, skateboarding, skiing, surfing, swimming, table tennis, tennis, or volleyball, or during training sessions related thereto.
- Data obtained by the
sensor module 102 may be processed in a variety of ways to yield useful information about the motion of a piece ofathletic equipment 104 during the activity. In some embodiments,sensor module 102 data may be processed to monitor changes in the spatial orientation of a piece ofathletic equipment 104. In other embodiment,sensor module 102 data may be processed to by reference to a predetermined correlation between movement data and an activity metric stored in a data structure. - With reference to
FIG. 9 , in one embodiment of the present invention, an individual 10 may use thesensor module 102 in themotion monitoring system 100 to determine a change in spatial orientation of the piece ofathletic equipment 104 according tospatial orientation process 400 as follows. - First, at
step 402, thesensor module 102 may detect movement of the piece ofathletic equipment 104. In one embodiment, movement of the piece ofathletic equipment 104 is detected based on acceleration data captured by theacceleration sensor 118 of thesensor module 102. In another embodiment, movement of the piece ofathletic equipment 104 is detected based on magnetic field data captured by themagnetic field sensor 120 of thesensor module 102. In yet another embodiment, movement of the piece ofathletic equipment 104 is detected based on both acceleration data and magnetic field data. - In one embodiment, the
magnetic field sensor 120 may be adapted to measure the strength and direction of magnetic fields in the vicinity of thesensor module 102. In another embodiment, themagnetic field sensor 120 may be adapted to measure the strength and direction of the Earth's magnetic field in the vicinity of thesensor module 102. In some embodiments, themagnetic field sensor 120 may be capable of measuring the magnitude and direction of a resultant magnetic vector for the total local magnetic field and/or for the local Earth's magnetic field. - If the monitored piece of
athletic equipment 104 is asoccer ball 106, the detected movement may consist of thesoccer ball 106 rolling on the ground as a result of being dribbled by the individual 10. - In some embodiments, the
sensor module 102 may then determine that the movement of the piece ofathletic equipment 104 indicates the occurrence of a movement to track. In one embodiment, the determination that the movement of the piece ofathletic equipment 104 indicates the occurrence of a movement to track occurs when a threshold data value is met for a predetermined period of time. For example, thesensor module 102 may determine that a movement of the piece ofathletic equipment 104 has resulted in a threshold acceleration and/or magnetic field change occurring for a predetermined period of time. - In some embodiments, the determination of the occurrence of a movement to track is an indication that the movement to track had already begun prior to the determination. In this case, it is still possible to capture all of the relevant data relating to the movement as the
sensor module 102 may temporarily record a stream of data in a buffer in the event that data that had recently been recorded may need to be examined or more permanently recorded in response to a determination that an occurrence of a movement to track is found. In other embodiments, the determination of the occurrence of a movement to track is an indication that the movement to track is about to begin in the near future. In some embodiments, thesensor module 102 is adapted to store data permanently or temporarily, and may further be adapted to store data for predefined periods of time in certain circumstances, such as when populating a data buffer. - If the monitored piece of
athletic equipment 104 is asoccer ball 106, the movement of thesoccer ball 106 as a result of the individual 10 swiftly kicking thesoccer ball 106 with theirfoot 12 in an attempt to make a goal may result in a determination that the motion of thesoccer ball 106 in response to the kick—which could include motion of thesoccer ball 106 before, during, and/or after the determination was made—should be tracked. - Next, as
step 404, in response to the determination of the occurrence of a movement to track, an initial spatial orientation of the piece ofathletic equipment 104 may be determined. In some embodiments, the determination of an initial spatial orientation of the piece ofathletic equipment 104 may be made by reference to a coordinate axis system. - A coordinate axis system is a useful analytical tool for monitoring changes in the spatial orientation of an object, such as piece of
athletic equipment 104.FIG. 10 illustrates an exemplary three-dimensional Cartesian coordinateaxis system 500 having three axes—an X axis, a Y axis, and a Z axis. Two vectors, “G” and “B,” are superimposed on the coordinateaxis system 500 illustrated inFIG. 10 . The G-vector 502 pointing in the —Y direction represents a gravity vector. The B-vector 504 represents a resultant magnetic field vector. -
FIG. 11 illustrates another exemplary three-dimensional Cartesian coordinateaxis system 550. Thissystem 550 defines six degrees of freedom for a rigid body, such as the piece ofathletic equipment 104. Six degrees of freedom refers to motion of a rigid body in three-dimensional space, namely the ability to move forward/backward, up/down, left/right (translation in three perpendicular axes) combined with rotation about three perpendicular axes (pitch, yaw, roll), as illustrated inFIG. 11 . - Returning to the discussion of
step 404 inFIG. 9 , in one embodiment, the determination of the initial spatial orientation of the piece ofathletic equipment 104 may be made with respect to agravity vector 502, such as that illustrated inFIG. 10 . In another embodiment, the determination of the initial spatial orientation of the piece ofathletic equipment 104 may be made with respect to an Earthmagnetic field vector 504, such as that illustrated inFIG. 10 . In other embodiments, the determination of the initial spatial orientation of the piece ofathletic equipment 104 may be made with respect to characterizations of the way that the piece of athletic equipment translated and rotated in three-dimensional space with six degrees of freedom, as explained with reference toFIG. 11 . - If the monitored piece of
athletic equipment 104 is asoccer ball 106, the determination of the initial spatial orientation of thesoccer ball 106 relative to the specific movement to be tracked (i.e., movement of thesoccer ball 106 resulting from the kick by a foot 12) may be defined, for example, as the spatial orientation of thesoccer ball 106 just before, at the moment of, or just after thesoccer ball 106 was swiftly kicked by the individual's 10foot 12, depending on the particular application and algorithms used. - At
step 406, after the determination of the initial orientation of the piece ofathletic equipment 104 at a first time has been made, a change in the spatial orientation of the piece ofathletic equipment 104 may be determined. In an embodiment, the determination of the change in the spatial orientation of the piece ofathletic equipment 104 atstep 406 may be made similarly to the determination of the initial orientation of the piece ofathletic equipment 104 atstep 404, except that additional information about changes in the orientation of thegravity vector 502 and/or themagnetic field vector 504 as the object moves may be additionally factored in. - If the monitored piece of
athletic equipment 104 is asoccer ball 106, the determination of the change in the spatial orientation of thesoccer ball 106 relative to the specific movement to be tracked (i.e., movement of thesoccer ball 106 resulting from the kick) may be defined, for example, as the change in spatial orientation of thesoccer ball 106 from the time that the initial orientation of thesoccer ball 106 was identified to a later point in time when thesoccer ball 106 is still moving or has ceased moving, depending on the particular application and algorithms used. - At
step 408, an activity metric is determined based on the change in the spatial orientation of the piece ofathletic equipment 104 determined instep 406. The nature of the activity metric may change based on the athletic activity that the individual 10 is participating in, as well as particular piece ofathletic equipment 104 that is being monitored. In one embodiment, the activity metric may relate to, for example, a launch angle, a rate of rotation, a ball trajectory, a speed, a jump height, a jump force, a jump distance, a jump trajectory, a kick force, a kick distance, an impact force, an impact location, a characterization of a specific type of athletic movement, or a reaction time measurement. In other embodiments, the activity metric may be, for example, the rate of rotation, the plane of rotation, the jump force, force profile (force acting upon the body of the athlete or the ground or the object), stroke information in tennis, swing profile in golf, baseball, hockey stick, kick profile of a leg orfoot 12, angle position of a bike pedal, power output of a cyclist, fatigue (tremors starting to occur in repeated motion, i.e., running, lifting swimming, rowing etc.), posture, throwing or arm swing technique, and shooting technique. - If the monitored piece of
athletic equipment 104 is asoccer ball 106, the change in the spatial orientation of thesoccer ball 106 resulting from the kick may be used to determine, for example, a launch angle of thesoccer ball 106, a rate of rotation of thesoccer ball 106, launch speed, estimated speed,foot 12 impact location on thesoccer ball 106, or similar metrics. - Finally, at
step 410, an output is provided that conveys the activity metric to the individual 10, a coach, a teammate, a spectator, or any other interested person. In one embodiment, the output may be an audible, visual, and/or haptic output. - In some embodiments of the present invention, instead of a desire to monitor changes in the spatial orientation of a piece of
athletic equipment 104 of interest, there may be a desire to correlate movements of pieces ofathletic equipment 104 to activity metrics based on a predetermined correlation stored in a data structure. With reference toFIG. 12 , in such an embodiment, the individual 10 may use thesensor module 102 in themotion monitoring system 100 to determine such correlations toathletic equipment 104 movement according tomovement correlation process 420 as follows. - First, at
step 422, thesensor module 102 may detect movement of the piece ofathletic equipment 104. This step may be carried out in a similar fashion to step 402 of thespatial orientation process 400, as described above. - If the monitored
object 104 is asoccer ball 106, the detected movement may consist of thesoccer ball 106 rolling on the ground as a result of being dribbled by the individual 10. - In some embodiments, the
sensor module 102 may then determine that the movement of the piece ofathletic equipment 104 indicates the occurrence of a movement to track. If the monitored piece ofathletic equipment 104 is asoccer ball 106, the movement of thesoccer ball 106 as a result of the individual 10 swiftly kicking thesoccer ball 106 with theirfoot 12 in an attempt to make a goal may result in a determination that the motion of thesoccer ball 106 in response to the kick—which could include motion of thesoccer ball 106 before, during, and/or after the determination was made—should be tracked. - Next, at
step 424, thesensor module 102 may record movement data in response to identifying a movement to track. In one embodiment, movement of the piece ofathletic equipment 104 is recorded based on acceleration data captured by theacceleration sensor 118 of thesensor module 102. In another embodiment, movement of the piece ofathletic equipment 104 is recorded based on magnetic field data captured by themagnetic field sensor 120 of thesensor module 102. In yet another embodiment, movement of the piece ofathletic equipment 104 is recorded based on both acceleration data and magnetic field data. - If the monitored piece of
athletic equipment 104 is asoccer ball 106, the movement of thesoccer ball 106 as a result of the individual 10 swiftly kicking thesoccer ball 106 may be recorded. - Next, at
step 426, thesensor module 102 may determine a correlation between the recorded movement data and an activity metric. In one embodiment, this determination may be based on correlation information stored in a data structure, such as a lookup table. - A lookup table is a data structure, usually an array or associative array, often used to replace a runtime computation with a simpler array indexing operation. The savings in terms of processing time can be significant, since retrieving a value from memory is often faster than undergoing relatively processing-expensive computation or input/output operation. Lookup table figures may be pre-calculated and stored in static program storage or pre-fetched as part of a program initialization phase.
- The nature of the correlation may depend on the particular application and algorithms used to establish the correlation. Also, the nature of the activity metric may change based on the athletic activity that the individual 10 is participating in, as well as particular piece of
athletic equipment 104 that is being monitored. In one embodiment, the activity metric may relate to, for example, a launch angle, a rate of rotation, a ball trajectory, a speed, a jump height, a jump force, a jump distance, a jump trajectory, a kick force, a kick distance, an impact force, an impact location, a characterization of a specific type of athletic movement, or a reaction time measurement. In other embodiments, the activity metric may be, for example, the rate of rotation, the plane of rotation, the jump force, force profile (force acting upon the body of the athlete or the ground or the object), stroke information in tennis, swing profile in golf, baseball, hockey stick, kick profile of a leg orfoot 12, angle position of a bike pedal, power output of a cyclist, fatigue (tremors starting to occur in repeated motion, i.e., running, lifting swimming, rowing etc.), posture, throwing or arm swing technique, and shooting technique. - If the monitored piece of
athletic equipment 104 is asoccer ball 106, the correlation between the recorded movement data and an activity metric may rely on correlation data stored in a data structure that was derived from a function that expresses a relationship betweensoccer ball 106 acceleration data andsoccer ball 106 launch speed metrics. In some embodiments, the function underlying the relationship betweensoccer ball 106 acceleration data andsoccer ball 106 launch speed may be based on empirical data for the specificmodel soccer ball 106. - Finally, at
step 428, an output is provided that conveys the activity metric to the individual 10, a coach, a teammate, a spectator, or any other interested person. This step may be carried out in a similar fashion to step 410 of thespatial orientation process 400, as described above. - The analytical frameworks outlined with respect to
FIG. 9 andFIG. 12 detailing the basicspatial orientation process 400 and the basicmovement correlation process 420, respectively may be used in embodiments of the present invention to monitor a piece ofathletic equipment 104 using asensor module 102. However, in some embodiments of the present invention, these basic analytical frameworks may include additional steps that may provide improved capabilities, thus offering the individual 10 engaged in athletic activities better tools to assess their activities. -
FIG. 13 illustrates anactive state process 440 that may be used to augment the basicspatial orientation process 400 or the basicmovement correlation process 420 outlined above. Theactive state process 400 may enable asensor module 102 to run in a plurality of states, one of which may be considered an active state. In one embodiment, the active state may be characterized by thesensor module 102 consuming more power during the active state than prior to the active state. In another embodiment, the active state may be characterized by thesensor module 102 sampling data from theacceleration sensor 118 at a higher rate during the active state than prior to the active state. In yet another embodiment, the active state may be characterized by thesensor module 102 permanently saving data in the active state, as opposed to only temporarily recorded data prior to the active state. In this way, enabling various states may allow thesensor module 102 to operate with reduced battery power, reduced processing power, or otherwise be more efficient. - With reference to
FIG. 13 , theactive state process 440 begins asstep 442. In one embodiment, the steps of theactive state process 440 may occur just prior to the steps of the basicspatial orientation process 400 or the basicmovement correlation process 420 so that these processes may be carried out with moreefficient sensor module 102 function. - At
step 442, thesensor module 102 may detect movement of the piece ofathletic equipment 104 at a first time. This step may be carried out in a similar fashion to step 402 of thespatial orientation process 400 or step 422 of themovement correlation process 420, as described above. - If the monitored piece of
athletic equipment 104 is asoccer ball 106, the detected movement may consist of thesoccer ball 106 rolling on the ground as a result of being dribbled by the individual 10. - Next, at
step 444, thesensor module 102 may determine that the movement of the piece ofathletic equipment 104 corresponds to a predetermined activation movement. In some embodiments, the predetermined activation movement may include a series of discrete movements such as, for example, a ball being bounced three times in series, the ball being thrown a predetermined height, the ball being kicked with a certain level of force, or a movement that results in the acceleration of thesensor module 102 exceeding and/or falling below a predetermined threshold in absolute terms or for a predetermined period of time. In one embodiment, movement of the piece ofathletic equipment 104 is detected based on acceleration data captured by theacceleration sensor 118 of thesensor module 102. In another embodiment, movement of theobject 104 is detected based on magnetic field data captured by themagnetic field sensor 120 of thesensor module 102. In yet another embodiment, movement of theobject 104 is detected based on both acceleration data and magnetic field data. - The step of determining that the movement of the piece of athletic equipment corresponds to a predetermined activation movement may include comparing acceleration data associated with the predetermined activation movement to acceleration data detected in association with the movement of the piece of athletic equipment. Alternatively, the step of determining that the movement of the piece of athletic equipment corresponds to a predetermined activation movement may include comparing timing data associated with the predetermined activation movement to timing data detected in association with the movement of the piece of athletic equipment.
- If the monitored piece of
athletic equipment 104 is asoccer ball 106, the predetermined activation movement could be, for example, movement of thesoccer ball 106 after it had been stationary for a predetermined period of time, thesoccer ball 106 being bounced three times, thesoccer ball 106 being thrown into the air a certain height of period of time, or a variety of other possible activation movements. - In some embodiments, the monitored piece of
athletic equipment 104 can be considered stationary when thesensor module 102 of the monitored piece ofathletic equipment 104 senses resultant acceleration of about 1G (i.e., resultant acceleration within a threshold tolerance of 1G, for example, within 5% of 1G). In some embodiments the monitored piece ofathletic equipment 104 can be considered stationary at times while being handled by an individual 10. For example, a basketball can be stationary for a period of time in which a basketball player takes a jump shot with ball (e.g., before release of ball from the hands of the individual 10, the ball can be considered stationary, where resultant acceleration sensed bysensor module 102 is about 1G). Also for example, the ball can be stationary for a period of time in which a baseball player performs a throw of ball (e.g., a period of time spanning the transition from rearward motion to forward motion of the individual's 10 throwing motion, where resultant acceleration sensed bysensor module 102 is about 1G). - Next, at
step 446, after determining that an activation movement has occurred, thesensor module 102 may enter the active state. As previously described, the active state may be characterized, for example, by thesensor module 102 consuming more power or sampling data at a higher rate during the active state than prior to the active state. - Finally, at
step 448, upon thesensor module 102 entering the active state, detection of movement of the piece of athletic equipment at a second time, as detailed atstep 402 of the basicspatial orientation process 400 or atstep 422 of the basicmovement correlation process 420. In this way, enabling various states may allow thesensor module 102 to operate with reduced battery power, reduced processing power, or otherwise be more efficient. -
FIG. 14 illustrates areference motion process 450 that may be used to augment the basicmovement correlation process 420 outlined above. Thereference motion process 450 may enable asensor module 102 to identify a matching athletic motion from a plurality of reference motions by comparing movement data, where the plurality of reference motions may be diverse in nature. In this way, the athletic motion identification capabilities of themovement correlation process 420 may be enhanced by enabling identification and tracking of diverse types of motions executed during an activity. - With reference to
FIG. 14 , thereference motion process 450 begins asstep 452. In one embodiment, the steps of thereference motion process 450 may effectively be substituted forstep movement correlation process 420 outlined above so that the correlation and identification capabilities are enhanced. - At
step 452, thesensor module 102 may record movement data (possibly in response to identifying a movement to track in a previous step, as outlined above). In one embodiment, movement of the piece ofathletic equipment 104 is recorded based on acceleration data captured by theacceleration sensor 118 of thesensor module 102. In another embodiment, movement of the piece ofathletic equipment 104 is recorded based on magnetic field data captured by themagnetic field sensor 120 of thesensor module 102. In yet another embodiment, movement of the piece ofathletic equipment 104 is recorded based on both acceleration data and magnetic field data. - If the monitored piece of
athletic equipment 104 is asoccer ball 106, the movement of thesoccer ball 106 as a result of the individual 10 swiftly kicking thesoccer ball 106 with theirfoot 12 may be recorded. - Next, at
step 454, thesensor module 102 may identify a matching athletic motion from a plurality of reference motions by comparing the movement data to data associated with the plurality of reference motions. In one embodiment, as withstep 428 of the basicmovement correlation process 420, the identification may be made at least in part based on correlation information stored in a data structure, such as a lookup table. - Particular to step 454, identification of the matching athletic motion may be by reference to a plurality of reference motions. In other words, at
step 454, the system is not limited to looking for a motion that matches a single motion (e.g., kicking asoccer ball 106 in an effort to score a goal). In some embodiments, the system is not limited to looking for a motion that matches a single class of motions (e.g., offensive soccer motions). In other embodiments, the system is not limited to looking for a motion that matches motions in a single sport (e.g., soccer motions). Alternatively, when the activity is a team sport, the matching athletic motion may be a motion commonly executed by a person during that team sport. - In one embodiment, one or more of the reference motions may include a series of discrete movements. In some embodiments, data associated with the plurality of reference motions may include acceleration data, magnetic field data, and/or timing data. Of course, the nature of the identifying matching athletic motion may depend on the particular application and algorithms used to establish the match. Also, the nature of the matching athletic motion may change based on the athletic activity that the individual 10 is participating in, as well as particular piece of
athletic equipment 104 that is being monitored. In one embodiment related to basketball, the matching athletic motion may be, for example, a pass motion, an shot motion, an jump-shot motion, a dunk motion, a post-up motion, a cross-over dribble motion, a shot blocking motion, a steal motion, or a rebound motion. - Finally, at
step 456, an output is provided that conveys the matching athletic motion to the individual 10, a coach, a teammate, a spectator, or any other interested person. This step may be carried out in a similar fashion to step 428 of themovement correlation process 420, as described above. In this way, the athletic motion identification capabilities of themovement correlation process 420 may be enhanced by enabling identification and tracking of diverse types of motions executed during an activity. - In other embodiments of the present invention, these above-described analytical frameworks may include additional steps that may provide additional capabilities, thus offering the individual 10 engaged in athletic activities additional tools to assess their activities. Exemplary additional analytical frameworks are disclosed in commonly owned U.S. patent application Ser. No. 13/446,982, filed Apr. 13, 2012 (which published as U.S. Patent App. Pub. No. 2013/0274040), the entirety of which is incorporated herein by reference thereto.
- By using the
motion monitoring system 100 including thesensor module 102 described above, embodiments of the present invention may advantageously enable the individual 10 (or their coach, teammate, or a spectator) to obtain this or other information about the motion of a piece ofathletic equipment 104 during or after the course of the athletic activity. - While various embodiments of the present invention are described in the context of the sports of soccer (i.e., football), the present invention is not so limited and may be applied in a variety of different sports or athletic activities including, for example, baseball, basketball, bowling, boxing, cricket, cycling, football (i.e., American football), golf, hockey, lacrosse, rowing, rugby, running, skateboarding, skiing, surfing, swimming, table tennis, tennis, or volleyball, or during training sessions related thereto.
- For baseball,

athletic equipment 104 during the course of the athletic activity. Once an activity metric or specific athletic movement has been identified by themonitoring system 100, to the extent that the activity metric or specific athletic movement was not entirely optimal/correct, thesystem 10 may further be employed to train or coach the individual 10 to improve their activity metric or specific athletic movement in the future. Determinations of what activity metric value or specific athletic movement characteristic is optimal/correct may be made automatically by thesystem 10 based on predetermined values, algorithms, or other data stored in a database, look-up table, or the like, or the determination may be made by a live trainer, coach, the individual 10 themselves, or another interested person with access to the activity metric value or specific athletic movement data. - For example, in embodiments where the monitored piece of
athletic equipment 104 is asoccer ball 106, where the change in the spatial orientation of thesoccer ball 106 resulting from a kick is used to determine, for example, a launch angle of thesoccer ball 106, a rate of rotation of thesoccer ball 106, launch speed, estimated speed, the location of the foot's 12 impact on thesoccer ball 106, or similar metrics, these determinations may be used by thesystem 10 to help the individual 10 improve their foot-ball impact, launch angle, rate of rotation, or launch speed in future kicks. Methods used to achieve improvements may be, for example, providing cross-training workouts or drills to the individual 10, providing soccer-specific workouts or drills to the individual 10, or prescribing a number of other training regimens. - Exemplary systems for calibrating data sensed by a
sensor module 102 are disclosed in commonly owned U.S. patent application Ser. No. 13/446,982, filed Apr. 13, 2012 (which published as U.S. Patent App. Pub. No. 2013/0274040), the entirety of which is incorporated herein by reference thereto. -
Individual 10 or another person may desire to know activity metrics of asport ball 106, for example, to learn the effects that actions of individual 10 have onsport ball 106, such as a kick or throw of thesport ball 106 by the individual 10.Motion monitoring system 100 may determine activity metrics such as trajectory ofsport ball 106, launch angle ofsport ball 106, rotation rate ofsport ball 106, orientation of rotation plane ofsport ball 106, orientation of rotation axis ofsport ball 106, travel speed ofsport ball 106, launch speed ofsport ball 106, force of a kick or other impact onsport ball 106, distance of travel ofsport ball 106, and maximum acceleration ofsport ball 106.Sensor module 102 may output data representative of such activity metrics, such as to a display device ofpersonal computer 304 or portableelectronic device 306. Such data may be outputted fromsensor module 102 in raw form (e.g., unprocessed signals fromacceleration sensor 118 and/or magnetic field sensor 120) or in representative form (e.g., data that results from processing signals fromacceleration sensor 118 and/or magnetic field sensor 120). In some embodiments,monitoring system 100 outputs a representation of one or more activity metrics in a manner perceivable byindividual 10 and/or another person. - As noted herein, in some embodiments
motion monitoring system 100 can determine and/or output a representation of instantaneous trajectory of asport ball 106 over a period of time or at a particular point in time, the instantaneous trajectory being a representation of the direction of motion ofsport ball 106 in motion. - In some embodiments,
motion monitoring system 100 can determine and/or output a representation of launch angle ofsport ball 106. In some embodiments, launch angle can be determined to correspond to instantaneous trajectory ofsport ball 106 at a point in time sufficiently close to initiation of motion ofsport ball 106, such as shortly aftersport ball 106 has been kicked or hit. In some embodiments, initiation of motion ofsport ball 106 is determined based on a sensed impulse acceleration exceeding a threshold. In some embodiments, launch angle can be determined to correspond to instantaneous trajectory ofsport ball 106 less than 150 ms (e.g., 100 ms to 150 ms) after initiation of motion ofsport ball 106. In some embodiments, launch angle can be determined to correspond to instantaneous trajectory ofsport ball 106 at the earliest time after initiation of motion ofsport ball 106 at which acceleration magnitude can be sensed. - In some embodiments, this time may immediately follow a period of less reliable data output by
acceleration sensor 118, where such data output is less reliable than data output byacceleration sensor 118 at other times. Such less reliable data output may be the result of, for example, a disturbance (e.g., railing) in sensed acceleration data (e.g., due to sudden change in acceleration, for example, upon an impact) or gain saturation of the acceleration sensor signal (e.g., a period during which the acceleration sensor outputs its maximum acceleration signal, because acceleration is higher than the maximum acceleration it can sense), which may result from, for example, the high initial acceleration ofsport ball 106 in reaction to an impact (e.g., a kick, a throw, a shot). In some embodiments, such less reliable acceleration data output may be experienced for a time (e.g., 100-150 ms) after impact of a kick (e.g., about 10 ms for the duration of kick impact, and about 90 ms to 140 ms after impact). - Launch angle can correspond to instantaneous trajectory as the angle of the vertical component of the direction of travel of a
sport ball 106 in free flight sufficiently close to initiation of motion ofsport ball 106. In some embodiments, free flight is determined based on acceleration data. Immediately upon entering free flight (e.g., uponsport ball 106 being thrown or kicked), acceleration data sensed byacceleration sensor 118 shows resultant acceleration of less than 1G (i.e., less than the acceleration due to gravity). For example, resultant acceleration may drop from 1G (e.g., in a stationary or non-free flight state) to 0.5G (e.g., in free flight). The time at which this drop takes place can be determined as the initiation of free flight. Continued free flight can be determined while resultant acceleration remains below 1G. In some embodiments, the magnitude of acceleration due to gravity can be predefined, or can be determined based on acceleration data sensed whilesport ball 106 is stationary. - The closer to initiation of motion that the angle of the vertical component of the direction of travel of
sport ball 106 in free flight is determined, the more representative of launch angle it may be. Beyond initiation of motion, the angle of the vertical component of the direction of travel ofsport ball 106 in free flight may change (e.g., decrease). In some embodiments, this change can be compensated for using a formula based on the instantaneous trajectory, speed, and time (after initiation of motion), to increase the accuracy of the launch angle determination. In some embodiments, the path ofsport ball 106 during a period of gain saturation (i.e., while the acceleration sensor is railed) can be determined based on magnetic field data sensed during that time. In some embodiments the launch angle at the moment of impact can be determined based on this path. - In some embodiments, instantaneous trajectory and/or launch angle of
sport ball 106 can be determined based on one or more of acceleration data and magnetic field data (e.g., sensed byacceleration sensor 118 and/or magnetic field sensor 120) at a first, earlier time, and one or more of acceleration data and magnetic field data (e.g., sensed byacceleration sensor 118 and magnetic field sensor 120) at a second, later time. In some embodiments, at the firsttime sport ball 106 is stationary, and at the secondtime sport ball 106 is in motion (e.g., motion ofsport ball 106 is initiated between the first time and the second time). - Exemplary systems for determining instantaneous trajectory and launch angle of a
sport ball 106 are disclosed in commonly owned U.S. patent application Ser. No. 13/446,982, filed Apr. 13, 2012 (which published as U.S. Patent App. Pub. No. 2013/0274040), the entirety of which is incorporated herein by reference thereto. - It is known that the direction of motion of a moving body is opposite to the direction of drag force applied to the moving body. In some
embodiments monitoring system 100 determines the relative (i.e., with respect to sensor module 102) direction of motion ofsport ball 106 to be opposite to the direction of resultant acceleration vector. - In some embodiments, to determine the absolute (i.e., with respect to the external coordinate system) direction of motion of sport ball 106 (e.g., instantaneous trajectory),
monitoring system 100 subtracts the angle of rotation ofsport ball 106 between the first time and the second time from the relative direction of motion ofsport ball 106. - In some embodiments, to determine launch angle of
sport ball 106,monitoring system 100 determines the angle of the vertical component of the absolute direction of motion ofsport ball 106, which is determined to correspond to launch angle ofsport ball 106. - As noted herein, in some
embodiments monitoring system 100 can determine and/or output a representation of rotation rate ofsport ball 106. Rotation rate is a measure of the angular velocity (ω) at whichsport ball 106 rotates, and can be expressed, for example, as the number of revolutions ofsport ball 106 per unit time, or the angular change ofsport ball 106 per unit time. - In some embodiments, to determine rotation rate of
sport ball 106,sensor module 102 of rotatingsport ball 106 can sense acceleration data viaacceleration sensor 118 at a first time and at a second time. Between the first time and the second time, sport ball 106 (including sensor module 102) rotates. Acceleration data sensed at the first time and the second time is a resultant acceleration vector created due to drag forces acting onsport ball 106. In some embodiments,monitoring system 100 normalizes the resultant acceleration vector at each of the first time and the second time (e.g., so that the resultant acceleration vector is between −1 and 1). Such normalization can provide a true orientation in space of the resultant acceleration vector. This normalization is performed on data from all (e.g., all three) axes of acceleration sensor 118 (such that the sum of the squares of the normalized values will always be 1). In some embodiments,monitoring system 100 determines the angle of each axis at the first time and at the second time by denormalizing the magnitude of the normalized value (e.g., calculating the cosine or arccosine of the value). In some embodiments,monitoring system 100 determines the change in each angle between the first time and the second time. In some embodiments,monitoring system 100 determines the rate of rotation based on the change in angle between the first time and the second time and the elapsed time between the first time and the second time. - In some embodiments, to determine rotation rate of
sport ball 106,sensor module 102 of rotatingsport ball 106 can sense acceleration data viaacceleration sensor 118 for a period of time. In some embodiments,monitoring system 100 can identify a repeating portion of the sensed acceleration data (e.g., the orientation of acceleration with respect to sensor module 102). In some embodiments,monitoring system 100 can identify a repeating portion of the sensed acceleration data by identifying successive similar orientations of such acceleration data (e.g., repeating peaks in data output representative of the orientation of acceleration) with respect tosensor module 102. In some embodiments,monitoring system 100 can determine the time period of a repeating portion of sensed acceleration data (e.g., the elapsed time between successive similar orientations of such acceleration data), which can represent the time period for a single revolution ofsport ball 106. In some embodiments,monitoring system 100 can calculate the inverse of the time period for a single revolution ofsport ball 106 and can determine this value to be the rotation rate ofsport ball 106. - As noted herein, in some embodiments
motion monitoring system 100 can determine and/or output a representation of the orientation of rotation ofsport ball 106, which may be represented the angle of the axis of rotation ofsport ball 106 and/or the angle of the plane of rotation ofsport ball 106. Axis of rotation is an axis throughsport ball 106 about whichsport ball 106 rotates. Plane of rotation is a plane orthogonal to axis of rotation. In some embodiments, angles can be determined based on acceleration data sensed byacceleration sensor 118 and magnetic field data sensed bymagnetic field sensor 120. - In some embodiments,
monitoring system 100 can determine one or both of angles by sensing orientation of resultant acceleration vector with respect tosensor module 102 at a first time (e.g., t1) and at a second time (e.g., t2, where the second time may be 20-30 ms after the first time). In some embodiments,monitoring system 100 can determine the orientation (with respect to sensor module 102) of the plane defined between the orientation of resultant acceleration vector with respect tosport ball 106 at the first time and the orientation of resultant acceleration vector with respect tosport ball 106 at the second time. In some embodiments,monitoring system 100 can define this plane to be the plane of rotation ofsport ball 106. In some embodiments,monitoring system 100 can determine the angle between plane of rotation and the orientation of gravity vector with respect tosensor module 102. In some embodiments,monitoring system 100 can calculate angles based on the angle between plane of rotation and the orientation of gravity vector using, for example, trigonometric calculations. - As noted herein, in some
embodiments monitoring system 100 can determine and/or output a representation of travel speed ofsport ball 106. Speed is a measure of the rate of change of the position ofsport ball 106, and can be expressed as the magnitude of a velocity vector ofsport ball 106. Speed ofsport ball 106 can be determined based on acceleration data sensed byacceleration sensor 118 whilesport ball 106 is in motion. Speed ofsport ball 106 can be determined for anytime sport ball 106 is in free flight. In some embodiments, speed is calculated shortly after initiation of motion (e.g., 50 ms after being kicked) in order to determine a near-maximum speed ofsport ball 106 in response to the initiation of motion. - In some embodiments,
sport ball 106 is determined to be in free flight at a given time. While in free flight,acceleration sensor 118 ofsensor module 102 may sense magnitude of acceleration ofsensor module 102, and thussport ball 106, with respect tosensor module 102. The magnitude of acceleration can be expressed as the magnitude of a resultant acceleration vector. In some embodiments, the acceleration sensed bysensor module 102 is substantially entirely due to the effects of drag (i.e., deceleration due to a drag force) onsport ball 106. - It is known that the direction of motion of a moving body is opposite to the direction of drag force applied to the moving body. Thus, in some embodiments the magnitude of acceleration sensed by
acceleration sensor 118 ofsensor module 102 is the magnitude of acceleration in the direction of motion ofsport ball 106. In some embodiments the magnitude of acceleration sensed byacceleration sensor 118 ofsensor module 102 is determined to be the magnitude of acceleration in the direction of motion ofsport ball 106. - Speed of
sport ball 106 in motion can be expressed as a function of the magnitude of acceleration ofsport ball 106. This functional relationship can be influenced by physical characteristics of sport ball 106 (e.g., mass, size, surface area, surface texture, material, shape, panel shape, moment of inertia), and thus may vary forsport balls 106 of different construction. This functional relationship can also be influenced by environmental conditions (e.g., ambient temperature, local pressure), indications of which may be received by monitoringsystem 100 from suitable environmental sensors (e.g., coupled tosport ball 106, incorporated intosensor module 102, coupled to a remote device) or input by an individual 10 via an interface of monitoring system 100 (e.g., an input ofpersonal computer 304 or portableelectronic device 306, such as, for example, a keyboard, microphone, or touchscreen). This functional relationship can also be influenced by dynamic characteristics ofsport ball 106 such as, for example, rotation of sport ball 106 (e.g., rotation rate and/or rotation angle), which can impart a Magnus effect onsport ball 106, influencing its speed. A Magnus effect can cause a curve or bend in the trajectory ofsport ball 106. - For a given sport ball 106 (and balls of the same or sufficiently similar construction), this functional relationship may be established by calculation (e.g., the relation between drag force and speed of a spherical object in free flight is speed=constant*log(drag)+constant), experimentation, or both, and may be expressed and/or stored as a data structure within
monitoring system 100, for example, as an algorithm, as a graphical curve, or as a lookup table. - In some embodiments, the functional relationship can be established (or augmented) by an individual 10 of
sport ball 106. For example, individual 10 may setsport ball 106 on the ground a distance from a wall or other object or structure.Individual 10 may input the distance intomonitoring system 100 via an interface thereof.Individual 10 may then kicksport ball 106 at the wall with theirfoot 12.Sensor module 102 may sense the time of initiation of free flight ofsport ball 106 assport ball 106 is impacted by individual's 10foot 12.Sensor module 102 may then sense thetime sport ball 106 makes contact with the wall (e.g., by an abrupt change in resultant acceleration, such as a drop to about zero). The distance traveled divided by the time of travel can be used to determine a representation of the speed ofsport ball 106 for the measured kick. Resultant acceleration (i.e., drag) can be sensed for the measured kick.Individual 10 may perform such operations multiple times, at the same or different distances, to establish an experimental data set, which can be used to derive a representation of the functional relationship between drag force and speed of thesport ball 106 in free flight. This representation of the functional relationship can be stored as a data structure withinmonitoring system 100 and subsequently referred to in order to determine speed ofsport ball 106 based on measured acceleration data, as described above. - Once the magnitude of acceleration of
sport ball 106 is sensed byacceleration sensor 118 ofsensor module 102,monitoring system 100 compares the magnitude of acceleration ofsport ball 106 to a data structure expressing the functional relationship between magnitude of acceleration and speed for the givensport ball 106, to determine speed of sport ball 106 (i.e., the speed that corresponds to the sensed acceleration magnitude in the data structure expressing the functional relationship). - A graphical curve and/or table can each be relied upon by monitoring
system 100 to determine speed ofsport ball 106, given the magnitude of acceleration ofsport ball 106. For example, given a magnitude of acceleration of A, both graphical curve and table could show a speed of B, and given a magnitude of acceleration of C, both graphical curve and table could show a speed of D. In some embodiments, if a given value for magnitude of acceleration does not have a corresponding magnitude of acceleration in the expression of the functional relationship (e.g., graphical curve or table), the speed may be determined by known techniques of mathematical approximation, such as, for example, rounding or interpolation. - In some embodiments,
monitoring system 100 can determine and/or output a representation of a flight time ofsport ball 106. In some embodiments, flight time can be determined based on acceleration data. For example, flight time can correspond to a period during which acceleration data sensed byacceleration sensor 118 shows resultant acceleration of less than 1G. For example,sensor module 102 may determine the time at whichsport ball 106 enters free flight (e.g.,monitoring system 100 may determine a flight initiation time corresponding to the time at which resultant acceleration drops below 1G), may determine a flight termination time corresponding to the time at which resultant acceleration returns to 1G, may calculate the elapsed time between the flight initiation time and the flight termination time, and may determine the elapsed time to be a flight time ofsport ball 106. - In some embodiments,
monitoring system 100 can determine and/or output a representation of distance of travel ofsport ball 106. In some embodiments,monitoring system 100 can determine distance of travel ofsport ball 106 for a flight ofsport ball 106 based on acceleration data. In some embodiments,monitoring system 100 can determine distance of travel based on flight time of sport ball 106 (which can be determined as described above) and travel speed of sport ball 106 (which can be determined as described above) during the flight time (e.g.,monitoring system 100 can determine the average speed ofsport ball 106 during flight). For example,monitoring system 100 can determine distance of travel for a flight ofsport ball 106 by multiplying average velocity during the flight by the flight time. - In some embodiments,
monitoring system 100 can determine a trajectory model (i.e., path of flight) for an instance of free flight ofsport ball 106, and may calculate the distance traversed bysport ball 106. In some embodiments,monitoring system 100 can determine the trajectory model based on conditions (e.g., activity metrics) of sport ball 106 (e.g., conditions at initiation of flight ofsport ball 106, and/or at a point in time thereafter). In some embodiments,monitoring system 100 can determine the trajectory model based on speed ofsport ball 106, launch angle ofsport ball 106, rotation plane ofsport ball 106, and rotation rate ofsport ball 106, each of which can be determined, for example, as described herein.Monitoring system 100 can calculate the distance traveled bysport ball 106 based on the trajectory model (e.g., by calculating the distance between beginning and end points of the trajectory model along the ground, or a plane representing the ground). In some embodiments, because the trajectory model can be determined based on conditions before completion of a flight ofsport ball 106,monitoring system 100 can determine a trajectory model for an instance of flight even in the event that free flight ofsport ball 106 is interrupted (e.g., by striking an object). In such a case,monitoring system 100 can determine an estimated distance traveled bysport ball 106, which can correspond to adistance sport ball 106 would have traveled had its flight not been interrupted. - In some embodiments,
monitoring system 100 can determine and/or output a representation of maximum acceleration ofsport ball 106. In some embodiments,monitoring system 100 can determine maximum acceleration ofsport ball 106 based on acceleration data. For example,monitoring system 100 can determine maximum acceleration ofsport ball 106 in flight using acceleration data sensed byacceleration sensor 118 ofsensor module 102. For example,monitoring system 100 can compare the magnitude of acceleration ofsport ball 106 for a time period at all times during the period (or a subset thereof) for which data is available, to identify the greatest magnitude of acceleration, which can be determined to be the maximum acceleration ofsport ball 106 during the time period. The time period for which maximum acceleration is determined can be any time period, for example, a single period of free flight, a selected time period, or the duration of an athletic contest. In some embodiments,monitoring system 100 is may filter out sensed magnitudes of acceleration of, around, or in excess of 1G, as such magnitudes may be due to gravity (e.g., in theevent sport ball 106 is not in free flight). -
Monitoring system 100 can output representations of activity metrics, including, for example, trajectory ofsport ball 106, launch angle ofsport ball 106, rotation rate ofsport ball 106, orientation of rotation plane ofsport ball 106, orientation of rotation axis ofsport ball 106, travel speed ofsport ball 106, launch speed ofsport ball 106, force of a kick or other impact onsport ball 106, impact location on thesport ball 106, distance of travel ofsport ball 106, and maximum acceleration ofsport ball 106, in a manner perceivable by individual 10 or other person (e.g., a coach, trainer, or spectator). Data generated within or received by any component ofmonitoring system 100 can be transmitted, processed, and output in any suitable manner, including those described herein. - For example, in some embodiments, representations of activity metrics can be output to a display of a portable electronic device (e.g., portable electronic device 306) or personal computer (e.g., personal computer 304). In some embodiments,
monitoring system 100 can determine and output, for example, representations of activity metrics in real time, representations of past activity metrics, representations of predicted activity metrics, representations of comparisons of a current (or most recent) value for an activity metric to a past value for that activity metric, representations of comparisons of one activity metric to a different activity metric, representations of comparisons of a value for an activity metric to a target value for the activity metric, representations of comparisons of a value for an activity metric ofsport ball 106 or individual 10 to a value for the same (or a different) activity metric for adifferent sport ball 106 or individual 10. - In some embodiments, representations of activity metrics can be presented (e.g., displayed on a display screen of any of the devices described herein) as functions of one another, or of other variables. For example, travel distance of
sport ball 106 can be presented as a function of launch angle. Also for example, activity metrics can be presented as a function of location (e.g., location on a playing field, proximity to a player, proximity to a goal), as a function of an event (e.g., scoring of a field goal, committing a foul), as a function of an environmental condition (e.g., ambient temperature, precipitation), or as a function of a physiological condition of an individual 10 (e.g., heart rate, body temperature). Information relating to such variables (e.g., location information, event information, environmental condition information, and physiological condition information) may be provided tomonitoring system 10 from appropriate sensors incorporated therein, or from elements outside ofmonitoring system 100 that are in communication withmonitoring system 100. - In some embodiments,
monitoring system 100 can determine and output representations in any perceivable way, for example, numerically (e.g., by outputting a value indicative of the activity metric or comparison), textually (e.g., by outputting a word or phrase indicative of the activity metric or comparison), graphically (e.g., by outputting a graph or other image indicative of the activity metric or comparison), or tabularly (e.g., by outputting a table indicative of the activity metric or comparison). - In some embodiments, activity metrics can be output in a game-like manner. Points or other positive or negative feedback may be determined and output based on values for activity metrics for
sport ball 106 and/orindividual 10. Comparisons based on such values or feedback can influence progress in the game. For example, such values or feedback may be compared to past values or feedback for thesame individual 10 orsport ball 106, and improvement may result in positive progress being made in the game (e.g., a higher “level” being designated to a game account of individual 10 or sport ball 106). Also for example, such values or feedback may be compared to values or feedback of a different individual 10 or sport ball 106 (including data of, or purported to be of, a professional athlete or other well-known person), and progress in the game may be determined based on that comparison. Also for example, such values or feedback may be compared to target values or feedback, and progress in the game may be determined based on that comparison. Also for example, in some embodiments, such activity metrics can govern capabilities of a virtual player in a virtual game, by being uploaded to or otherwise accessed by the game (e.g., the maximum ball speed of an individual's 10 kick ofsport ball 106 may limit the maximum virtual ball speed of a virtual avatar of the individual in a virtual game). - In some embodiments, a plurality of monitored
individuals 10 may interact with one or more of sport balls 106 (e.g., during a soccer game). Activity metrics derived from each of the plurality ofindividuals 10 and activity metrics derived from ball(s) can be similarly compared, combined, and/or represented as described above. Such comparison, combination, and/or representations can be made based on each individual 10 considered separately, on a subset ofindividuals 10 grouped together (e.g., a team, midfielders of a team), or on all monitoredindividuals 10. In a game setting, such comparison, combination, and/or representations can be correlated to game events, such as a goal, asport ball 106 traveling out-of-bounds, a penalty kick, or a jump ball, which can be output in relation to contemporaneous activity metrics ofindividuals 10 as described. - Such comparing, combining, and/or representing data derived from monitoring
sport ball 106 and from monitoringindividuals 10 interacting withsport ball 106 can provide benefits to, for example, theindividuals 10 participating in an athletic activity, coaches, spectators, physicians, and game officials. Such persons may interact or work together during a session of athletic activity for a variety of reasons. - For example, it may be desired that a coach monitors the performance of the
individuals 10 and makes recommendations or otherwise influences their performance in order to maximize the individuals' 10 fitness level. Alternatively or additionally, it may be desired that the coach monitors and influences theindividuals 10 to help maximize the effectiveness of theindividuals 10 in the athletic activity. Further, it may be desired that the coach monitors and influences theindividuals 10 to help maximize the probability of success in the athletic activity (where success may be, for example, defeating an opposing team in a game, such as, for example, soccer, or achieving/maintaining a desired level of fitness for one ormore individuals 10 participating in the athletic activity). A session of athletic activity may include, for example, a training session (e.g., a field session, a gym session, a track session) or a competitive session (e.g., a soccer match or a basketball game). - In some embodiments, the coach may monitor the
individuals 10 andsport ball 106 and may provide feedback to theindividuals 10 in order to track and maintain or improve the individuals' 10 health, safety, and/or performance. - In some embodiments,
monitoring system 100 can be applied as described herein to a standalone sensor that can be affixed to any implement, including, for example, the objects described herein (e.g., as an aftermarket upgrade). - Building on the above description, a description of various exemplary methods of using the
motion monitoring system 100 of the present invention to monitor changes in the spatial orientation or movement of a piece ofathletic equipment 104, or to determine a correlation betweensoccer ball 106 movement data and point ofimpact 150 on asoccer ball 106, is now provided below. - As illustrated in
FIG. 15 , a soccer kick can involve a series of complex motions by an individual 10 leading up to the striking of thesoccer ball 106 by the individual's 10foot 12. Generally speaking, under ideal conditions when an individual 10 is attempting to kick a goal, the individual 10 may approach thesoccer ball 106 by taking several steps toward thesoccer ball 106. Depending on the nature of the kick, the individual 10 may approach thesoccer ball 106 straight on with respect to the intended flight path ofsoccer ball 106, or may approach thesoccer ball 106 at an angle with respect to the intended flight path of thesoccer ball 106. Next, as illustrated inFIG. 15 , it is often desirable for the individual 10 to land their “plant foot” (i.e. thefoot 12 not kicking the soccer ball 106) to the side of and directly in the middle of thesoccer ball 106, with theplant foot 12 pointing toward the intended target. The individual 10 then ideally keeps their head down and leans their body into the kick, swing their kickingfoot 12 into thesoccer ball 106 and continuing to follow through, as shown inFIG. 15 . - Depending on the intended flight path and other motion characteristics of the
soccer ball 106, the individual 10 may need to utilize a particular approach and ball-striking mechanics. Soccer players know from experience that a relationship exists between the location of the point of impact between theirfoot 12 and asoccer ball 106 and motion characteristics of thesoccer ball 106 during and after it is kicked.FIG. 16 illustrates anexemplary strike zone 140 and point ofimpact 150 on asoccer ball 106 resulting from a kick by an individual's 10foot 12. When an individual 10 kicks asoccer ball 106, the impact typically results in deformation of both the individual's 10 foot 12 (or rather, the footwear covering their foot 12) and of thesoccer ball 106. Deformation of thesoccer ball 106 is more significant and visually apparent—a surface of thesoccer ball 106 typically becomes indented or flattened in response to a sufficiently swift kick. - The
strike zone 140 shown inFIG. 16 represents an area of the surface of thesoccer ball 106 where contact with a portion of the individual's 10foot 12 and/or deformation of thesoccer ball 106 may occur during a kick. The point ofimpact 150 shown inFIG. 16 occurs within the bounds of thestrike zone 140, and represents the location on the surface of thesoccer ball 106 that approximately coincides with the center of the area of thefoot 12 in contact with thesoccer ball 106. Note that the point ofimpact 150 is in alignment with an exterior marking 202 of thesoccer ball 106, as first described in connection withFIG. 5 . Corresponding markings are illustrated on the foot 12 (encased in a soccer boot) inFIG. 16 to show an exemplary position on thefoot 12 where thefoot 12 may impact thesoccer ball 106. - Embodiments of the present invention provide an analytical framework for analyzing motion characteristics of
sport balls 106, such as asoccer ball 106, including analyzing the relationship between the location of the point ofimpact 150 between an individual's 10foot 12 and asoccer ball 106 and motion characteristics of thesoccer ball 106 during and after it is kicked. Examined motion characteristics include ball speed, ball spin rate, ball spin axis, and ball launch angle. -
FIG. 17 provide a useful diagram for characterizing the locations of points ofimpact 150 on the surface of asoccer ball 106. In this exemplary figure, asoccer ball 106 viewed from the front has been divided into four quadrants: I, II, III, and IV. A first point ofimpact 150, a second point ofimpact 152, and a third point ofimpact 154 are also illustrated. The precise location of the point ofimpact foot 12 and asoccer ball 106 is correlated to motion characteristics of theball 106 including ball speed, ball spin rate, ball spin axis, and ball launch angle. - For example, if the
soccer ball 106 is kicked straight on such that the point of impact corresponds to point 150 inFIG. 17 —i.e. aligned with the dead center of thesoccer ball 106 where quadrants I, II, III, and IV meet—substantially all of the energy from the foot-ball impact will transmitted as a linear displacement. In other words, thesoccer ball 106 will be launched at a relatively high speed with little or no spin, a relatively level spin axis, and a relatively flat launch angle. - Alternatively, if the if the
soccer ball 106 is kicked far off to one of its sides relative the individual's 10 approach and the intended flight path such that the point of impact corresponds to point 152 inFIG. 17 —e.g. aligned with the “equator” ofsoccer ball 106 but off to the side in the direction of quadrants I and IV—substantially all of the energy that is transmitted will impart spin on thesoccer ball 106. In other words, thesoccer ball 106 will be launched at a relatively low speed with relatively high spin, and still with a relatively level spin axis and a relatively flat launch angle. - Finally, if the if the
soccer ball 106 is kicked somewhat off to one of its sides and somewhat below the level of the “equator” of thesoccer ball 106 such that the point of impact corresponds to point 154 inFIG. 17 —e.g. off center of thesoccer ball 106 but located relatively centrally within quadrant III—the energy that is transmitted will impart both speed and spin on thesoccer ball 106. In other words, thesoccer ball 106 may be launched at a relatively moderate speed with relatively moderate spin, but this time with a tilted spin axis and a relatively higher launch angle. - Several different empirical methods can be used to identify
strike zones 140 and points ofimpact 150 forsoccer balls 106 kicked byindividuals 10. In one embodiment, a quadrant grid similar to the one depicted inFIG. 17 could be drawn onto the surface ofsoccer balls 106 and oriented toward the intended flight path of thesoccer ball 106, and a visual identifying substance such as a food-grade dye can be applied to individuals' 10 feet 12 (or footwear). After a suitable sample of kicks is obtained, the locations ofstrike zones 140 and points ofimpact 150 forsoccer balls 106 kicked byindividuals 10 can be identified based on the locations of dye markings on thesoccer balls 106 with respect to the applied grids. In the case where themarked soccer balls 106 are outfitted withsensor modules 102 of the present invention, measurements can be taken during the kicks to identify motion characteristics of interest such as ball speed, ball spin rate, ball spin axis, and ball launch angle. - In another embodiment, a substance such as a rapidly evaporating alcohol can be applied to individuals' 10 feet 12 (or footwear), and monitored kicks can be recorded with an infrared camera. In this embodiment, the locations of
strike zones 140 and points ofimpact 150 for thesoccer balls 106 kicked byindividuals 10 can be identified based on an analysis of the recorded images of the locations of evaporating alcohol on thesoccer ball 106, as sensed by local changes in temperature caused by the evaporation. - It is possible to use
soccer balls 106 havingsensor modules 102 such as those described above to obtain ball speed, ball spin rate, ball spin axis, and ball launch angle data using such methods. Based on these experimental data obtained by these methods, given a suitably large and representative sample and suitably precise measurement techniques, and assuming the energy transfer between thefoot 12 and thesoccer ball 106 depends solely on the inertial and elastic properties of the soccer ball 106 (which are constant), it is also possible to undertake a multi-variable regression analysis to link ball speed, ball spin rate, ball spin axis, and ball launch angle data to points ofimpact 150 location data for asoccer ball 106. In other embodiments, other methods such as high speed video analysis can be used as well to obtain the ball movement characteristics, and this information can be used to define the variables for a multi-variable regression analysis. - Regression analysis is a statistical process for estimating the relationships among variables. Regression analysis can be used to fit a predictive model to an observed data set of values. After developing such a model, if additional values of one or more variables (e.g. ball speed, ball spin rate, ball spin axis, ball launch angle, or point of impact 150) can be determined, the fitted model can be used to make a prediction of the values of unknown variables. When building a suitable model, given variables that may be related, regression analysis can be applied to, for example, quantify the strength of the relationships between the various variables, to assess which variables may have no relationship at all, or to identify which subsets of the variables contain redundant information.
- In one embodiment of the present invention, a linear regression analysis can be employed to predict the relationship between ball speed, ball spin rate, ball spin axis, ball launch angle, or point of
impact 150. In linear regression, data are modeled using linear predictor functions, and unknown model parameters are estimated from the data. Exemplary results of a linear regression analysis correlating points of impact obtained empirically to points of impact determine from applying a linear regression function tosensor module 102 data are illustrate inFIG. 18 . - In another embodiment of the present invention, the regression analysis can alternatively rely on a tool known as a regression tree. A regression tree is a predictive model that maps observations about an item to conclusions about the item's target value. The goal is to create a model that predicts the value of a target variable based on several input variables. A tree can be derived by splitting the source set into subsets based on an attribute value test. This process is repeated on each derived subset in a recursive manner called recursive partitioning. The recursion is completed when the subset at a node has all the same value of the target variable, or when splitting no longer adds value to the predictions. A portion of an exemplary regression tree for correlating ball speed, ball spin rate, ball spin axis, ball launch angle, and point of
impact 150 is shown inFIG. 19 . In this figure, each x(n) variable represents one of thesoccer ball 106 motion variables, while the leafs of the regression tree represent an outcome variable after applying the regression conditions for a given branch. - Once a regression analysis results in a model that establishes a relationship between ball speed, ball spin rate, ball spin axis, ball launch angle, and point of
impact 150, measured or calculated values of some variables can be used to determine others that are unknown. In on embodiment of the present invention, data from asensor module 102 of asoccer ball 106 may be used to determine ball speed, ball spin rate, ball spin axis, and ball launch angle, for a given kick, and this data may be used to determine a point ofimpact 150 for the kick. - In one embodiment of the present invention, a regression analysis can be used to determine a point of
impact 150 for a kick based on acceleration data obtained for asport ball 106, such as asoccer ball 106. The acceleration data may be obtained from asensor module 102 of thesport ball 106, or from another source. In other embodiments, the regression analysis can be used to determine a point ofimpact 150 for a kick based on other data such as magnetometer data, angular momentum sensor data, or multiple types of data. - In an exemplary embodiment, as illustrated in
FIG. 20 , aregression analysis process 460 begins atstep 462 by receiving acceleration data. Atstep 464, the regression analysis determinessoccer ball 106 speed. Atstep 466, the regression analysis determinessoccer ball 106 spin rate. Atstep 468, the regression analysis determinessoccer ball 106 spin axis. Atstep 470, the regression analysis determinessoccer ball 106 launch angle. Each of these parameter determining steps may be conducted in accordance with the discussion provided above regarding obtaining these parameters. Finally, atstep 472, the regression analysis determines the location of a point ofimpact 150 on thesoccer ball 106. - As noted above, the regression analysis may rely on a regression tree. A regression tree may be used when linear regression techniques do not yield suitable predictive results. The regression tree is a model that can predict the value of a point of
impact 150 based on ball speed, ball spin rate, ball spin axis, and ball launch angle derived, in one embodiment, from acceleration data. In some embodiments, the regression tree can provide local data correlations that are not valid globally. The key is fitting a given set of input data into a particular portion of the regression tree where a good fit among the data can be found. For example, one branch of the regression tree may be a good fit for a kick with a high spin, low speed kick, while another branch of the regression tree may be a good fit for a kick with a low spin and high speed. Additional variables can be added to the analysis in various branches of the tree. But at some point, adding new variables requires significantly more data analysis while giving little added accuracy. In other words, at some point continuing to split new branches of the tree no longer adds value to the predictions. - In one exemplary embodiment of the present invention, as illustrated in
FIG. 21 , the best method for determiningsoccer ball 106 speed (as explained with reference to step 464 ofFIG. 20 ), for a given kick may depend on whether an underlying variable is above a given threshold. For example, in an embodiment, aspeed determination process 480 begins at step 482 (which may correspond to step 464 ofFIG. 20 ) when speed is to be determined. Atstep 484, a determination is made as to whether the spin rate of thesoccer ball 106 is above a certain threshold. In other embodiments, other variable thresholds may be employed. In one embodiment, a threshold of five revolutions per second may be used. Kicks where thesoccer ball 106 is determined to be rotating less than five revolutions per second may be deemed “slow spin” kicks, while kicks where thesoccer ball 106 is determined to be rotating more than five revolutions per second may be deemed “high spin” kicks. - In one embodiment, as illustrated in
step 486 ofFIG. 21 , if the spin rate of thesoccer ball 106 is above the five revolutions per second threshold, the regression analysis may proceed by analyzing the peak-to-peak acceleration output from an acceleration sensor, such assensor module 102. The peak-to-peak acceleration may consist of difference between the highest and lowest acceleration readings of resultant acceleration values. In the case of a multi-axis accelerometer (e.g. a triaxial accelerometer), the resultant acceleration values could factor in readings from each axis of the accelerometer. - In another embodiment, however, as illustrated in
step 488 ofFIG. 21 , if the spin rate of thesoccer ball 106 is not above the five revolutions per second threshold, the regression analysis may proceed by calculating root mean squares of the peak-to-peak acceleration. A root mean square of a value is a scalar measure of the magnitude of a varying quantity of the value. Root mean squares of the peak-to-peak acceleration values may be calculated for low-spin kicks because acceleration output behaves linearly under such conditions. In addition, atstep 490, the regression analysis analyzes both the root mean squares of the peak-to-peak acceleration values and spin data itself to determinesoccer ball 106 speed. Factoring in spin data corrects for some of the uncertainty in the speed calculations introduced by virtue of having to apply root mean squares of the peak-to-peak acceleration values. - Regardless of whether the kick was over or under the five revolutions per second spin threshold, the outcome of
speed process 480 can be fed into a general regression analysis as specified inregression process 460 ofFIG. 20 in order to determine a point ofimpact 150 for a kick. - In one embodiment of the present invention, the
soccer ball 106 must be in a free flight state after being kicked in order for thesensor module 102 to provide accurate data forsoccer ball 106 motion characteristic determinations. In other embodiments, themotion monitoring system 100 is able to make accurate data forsoccer ball 106 motion characteristic determinations even when thesoccer ball 106 in not in a free flight state after being kicked. - One non-free flight state after a
soccer ball 106 is kicked is known as a “grounder,” which occurs when thesoccer ball 106 is kicked and rolls or repeatedly bounces across the ground. Another non-free flight state after asoccer ball 106 is kicked is known as a “toe scoop,” which occurs when thesoccer ball 106 is not truly kicked but actually scooped relatively slowly by thefoot 12 and then released; thesoccer ball 106 is not truly impacted, just scooped—in a non-free fall state—and tossed. - In one embodiment, when the
motion monitoring system 100 determines that a grounder or toe-scoop has occurred, the individual 10 will be given a general error message. In another embodiment, themotion monitoring system 100 will specifically inform that the individual 10 that a grounder or a toe-scoop has been kicked. A more specific error message may prevent the individual 10 from losing confidence in thesystem 100 if the individual 10 assumed that any general error resulted from malfunction of the device, and not the individual's 10 improper grounder kick. - As previously noted with respect to
FIG. 8 , in some embodiments of the present invention, asport ball 106 having asensor module 102 may communicate with a portableelectronic device 306 of themotion monitoring system 100, such as a smart phone, that is also carried by the individual 10 during the athletic activity. As illustrated byFIGS. 22-49 , various software modules of asport ball 106 motion monitoring portableelectronic device 306 software of the present invention may support graphical user interfaces (GUIs) through which an individual 10 can interact with thesport ball 106 motion monitoring system. - In an embodiment of the present invention, the portable
electronic device 306 may take the form of a mobile phone and may include at least a processor, a memory, user input controls, a positioning system receiver, a wireless wide area network (WWAN) transceiver, a visual display, and an audio unit. A visual display in the form of a LCD screen, and user input controls in the form of a physical keyboard and a scroll ball may be present. - The memory of the portable
electronic device 306 may be adapted to store application programs used to implement aspects of the functionality of themotion monitoring system 100 described herein, such as asport ball 106motion monitoring system 100 portableelectronic device 306 software application. Thus, the application software may be stored, for example, in the memory of the portableelectronic device 306. Alternatively, those of skill in the art will understand that all or part of the software may be stored on theserver 302 and accessed over thenetwork 300 and run remotely as a mobile web application. - This
sport ball 106motion monitoring system 100 portableelectronic device 306 software application includes a number of different software modules capable of providingsport ball 106 motion monitoring services toindividuals 10 usingsport balls 106 or other pieces of athletic equipment equipped withsensor modules 102. In one embodiment of the present invention, these modules include a kick it module, a get better module, a challenges module, and a record book module. Each module may support one or more GUIs capable of being presented to an individual 10 using thesport ball 106motion monitoring system 100. - A GUI may offer, for example, graphical elements, visual indicators, and/or text to represent information and actions available to the individual 10. The individual 10 may use a physical input device, such as keyboard or scroll ball to interact with the GUI of the portable
electronic device 306. Alternatively, the individual 10 may use a touch screen to interact directly with what is displayed. Various touch screens such as, for example, resistive or capacitive touch screens, may be employed. - Those skilled in the art will appreciate that alternative or additional software modules and sub-modules may be implemented in order to provide or extend the described or additional functionalities to the individual 10 using the portable
electronic device 306. For example, the software configuration of software stored on a portableelectronic device 306 may include a portable device operating system, which may be one of the commercially available mobile phone operating systems such as, for example, BlackBerry OS, iPhone OS, Windows Mobile, Symbian, LINUX, WebOS, or Android. The portable device operating system may also have an associated application programming interface through which middleware and application programs may access the services of the operating system. - The various modules of the
sport ball 106motion monitoring system 100 of the present invention may support GUIs through which an individual 10 can interact with thesport ball 106motion monitoring system 100 using the portableelectronic device 306 just prior to and/or during an activity. As will be appreciated by those of skill in the art, in one embodiment the GUIs may be supported by a mobile device application being run on the portableelectronic device 306. In another embodiment, the GUIs may appear as web pages provided by theserver 302 via a website that may be accessible to the individual 10 over thenetwork 300 using a web browser on their portableelectronic device 306. - In order to access the features of embodiments of the present invention just prior to or during a physical activity, the individual 10 using the portable
electronic device 306 may power on their portableelectronic device 306 if it is not already in a powered up state. In some embodiments, it may be necessary for the individual 10 to manipulate user input controls to entersport ball 106motion monitoring system 100 mode to access the application software. - The first time the
sport ball 106motion monitoring system 100 application is launched, a start module may prompt the individual 10 to, for example, select a preferred language, enter a password to proceed, link their portableelectronic device 306 to a web account previously set up via theserver 302. The individual 10 may also be prompted to enter information such as, for example, preferred unit preferences, personal information such as the individual's 10 age, height, weight, and sex, and/or the individual's 10 desired voice training options. - The start module may present a
menu 600 GUI, as illustrated inFIG. 22 . During subsequent launches of the software application, themenu 600 may be presented to the individual 10 immediately upon launch. Themenu 600 may include several icons or indicia corresponding to the kick it, get better, challenges, and record book modules, as well as icons or indicia corresponding to settings or help features, as illustrated inFIG. 22 . After launching the application software, the individual 10 may cause different GUI pages to be provided by different modules by selecting their corresponding icons using user input controls. Additional icons corresponding to sub-modules or program wizards associated with a particular module may pop up or otherwise be displayed to the individual 10 if the individual 10 selects, swipes, or hovers over a module icon with a Cursor. -
FIG. 23 is an exemplary GUI window that may be provided by the kick it module. This GUI window may display aball icon 602 that may be used to convey various pieces of information to the individual 10. In addition, the GUI window may display aselection icon 604 for indicating which foot 12 (left or right) the individual 10 is going to be kicking asport ball 106 with. Before the individual 10 can begin to use themotion monitoring system 100, they must successfully pair the portableelectronic device 306 to asport ball 106, such as asoccer ball 106 having asensor module 102. Pairing is a process used in computer networking that helps set up an initial linkage between computing devices to allow communications between them. Pairing may occur wirelessly via a personal area network or local area network using, for example, the Bluetooth wireless protocols. The kick it module may prompt the individual 10 to pair their portableelectronic device 306 to asoccer ball 106, and may display updates to the individual 10 as to the status of the pairing. Updates may include notifying the individual 10 that the portableelectronic device 306 is attempting to connect to thesoccer ball 106, that a connection has been made, or that a connection cannot be made. In one embodiment, these prompts or notifications may appear in theball icon 602. - Once the portable
electronic device 306 and thesoccer ball 106 have been successfully paired, the individual 10 is ready to monitor a kick using themotion monitoring system 100. Prior to attempting a kick, however, the individual 10 may be presented with one or more tips in using themotion monitoring system 100. In some embodiments the individual 10 is provided with the tips automatically, while in other embodiments the individual 10 must request the tips my indicating a user input. Tips may include, for example, instructions on how to position and orient thesoccer ball 106 on the ground such that certain indicia on the surface of thesoccer ball 106 are aligned with external elements such as the ground, the individual's 10 desired approach to thesoccer ball 106, and/or the individual's 10 intended target or goal. In some embodiments, properly placing and orienting thesoccer ball 106 will ensure that thesensor module 102 of thesoccer ball 106 is properly aligned and calibrated so that data readings from thesoccer ball 106 will be accurate. - Other tips may include instructions on how the
soccer ball 106 must be kicked so as to obtain meaningful and accurate monitoring results. For example, in one embodiment, instructions may include kick distance and height limitations, such as that theball 106 must be kicked at least ten yards and at least two feet off of the ground to successfully track the kick. Still other tips may include turning up the volume on the individual's 10 portableelectronic device 306 for an optimal experience. - After any tips have been presented, or in the absence of tips, the individual 10 may be presented with a prompt to tap the
ball icon 602 when they are ready to monitor a kick using themotion monitoring system 100. For example,FIG. 24 is an exemplary GUI window that may be provided by the kick it module instructing the individual 10 to tap theball icon 602 when they are ready to monitor a kick. If not previously selected, the individual 10 may activate aselection icon 604 for indicating which foot 12 (left or right) the individual 10 is going to be kicking asoccer ball 106 with. - In response to receiving an indication that the individual 10 is ready to monitor a kick (e.g. the individual 10 taps the ball icon 602), the portable
electronic device 306 may communicate with thesoccer ball 106 having asensor module 102 to notify thesoccer ball 106 to expect a kick. In one embodiment, thesoccer ball 106 may prepare for an upcoming kick by adjusting its power consumption, adapting its processing, begin data recording, calibrate its sensors, or other operation. In another embodiment, thesoccer ball 106 may send a return signal to the portableelectronic device 306 to indicate that thesoccer ball 106 is ready to be kicked. - At this stage, the individual 10 may kick the
soccer ball 106. As previously noted with respect toFIG. 17 , a soccer kick can involve a series of complex motions by an individual 10 leading up to the striking of thesoccer ball 106 by the individual's 10foot 12. Depending on the intended flight path and other motion characteristics of thesoccer ball 106, the individual 10 may need to utilize a particular approach and ball-striking mechanics. - When the
soccer ball 106 is kicked, thesensor module 102 is capable of recording movement date associated with the kick, as described above with respect toFIGS. 8-21 . Thesoccer ball 106 having thesensor module 102, alone or in combination with the portableelectronic processing device 306, may be capable of determining motion characteristics of thesoccer ball 106 including ball speed, ball spin rate, ball spin axis, and ball launch angle. - In an embodiment of the present invention, is response to receiving the indication from the portable
electronic device 306 that the individual 10 is ready to monitor a kick, the pairedsport ball 106 may begin sampling data from thesensor module 102 at a predetermined rate. For example, in embodiments where thesensor module 102 includes one ormore acceleration sensors 118, thesport ball 106 may sample data from theacceleration sensors 118 at a rate of 1 kHz. In one embodiment, thesport ball 106 may continue sampling data from theacceleration sensors 118 at a rate of 1 kHz and saving the acceleration data into afile 700 on a memory device of thesport ball 106 indefinitely, until a predetermined amount of required memory is reached, or until all of the kick monitoring session is complete. - In another embodiment, as illustrated in
FIGS. 50A-50C , thesport ball 106 may employ a data sampling system that relies on both afile 700 on a memory device and a separate buffer data structure, such as acircular buffer 702 of fixed size that is significantly smaller than the size of thefile 700 on the memory device. In this embodiment, in response to receiving the indication from the portableelectronic device 306 that the individual 10 is ready to monitor a kick, thesport ball 106 may sample data from theacceleration sensors 118 at a rate such as 1 kHz and continually save the acceleration data into thecircular buffer 702, overwriting previous data as necessary, as shown inFIG. 50A . - In an embodiment, the
sport ball 106 may employ a compression algorithm to optimize memory utilization and post kick data analysis. The sport ball periodically analyzes the sampled data in thecircular buffer 702 to determine when to alter the rate at which samples are saved into memory based on the variability of the data. If thesport ball 106 determines that the data has a low variability, thesport ball 106 may periodically save low variability values into thefile 700 on the memory device of thesport ball 106 at a rate as infrequent as 1 Hz, as shown inFIGS. 50A and 50B . This practice may allow thefile 700 on the memory device to take up less memory space than if the sampled data were saved directly to thefile 700 on the memory device of thesport ball 106 at a much higher rate such as 1 kHz. InFIGS. 50A-50C , saveddata 704 from the accelerometer is identified byreference numeral 704, while low variability values 706 (e.g. a 1G acceleration due solely to gravity) are identified byreference numeral 706. In one embodiment, the compression algorithm can adjust the data save rate dynamically in a way that correlates with the signal variability. - On the other hand, if the
sport ball 106 determines that the acceleration data has become highly variable, thesport ball 106 may begin saving the sampled data directly into thefile 700 on the memory device of thesport ball 106 instead of to thecircular buffer 702, as shown inFIG. 50B . In addition, at the point in time when thesport ball 106 begins saving the sampled data directly into thefile 700, thesport ball 106 may also insert some or all of the data existing at that point in time in thecircular buffer 702 into thefile 700 just ahead of the new sampled data, as shown inFIG. 50C . In this way, thefile 700 on the memory device is able to capture acceleration data at each point in time and only in the highest fidelity necessary at each moment in time for later post kick analysis. - While the above described data processing is occurring at the
sport ball 106, in an embodiment of the present invention, after transmitting an indication to thesport ball 106 that the individual 10 is ready to monitor a kick, the portableelectronic device 306 may communicate with thesport ball 106 to download saved data from thefile 700 on the memory device of thesport ball 106. In another embodiment, the portableelectronic device 306 may first seek to determine how much data is presently stored in thefile 700 on the memory device of thesport ball 106. In some embodiments, this sort of communication may occur periodically, such as once every 100 or 200 milliseconds. In one embodiment, the communication to determine how much data is presently stored in thefile 700 on the memory device may occur every 100 or 200 milliseconds until the portableelectronic device 306 receives data indicating that the memory device has reached a certain level of capacity, such as being 2% full, 25% full, 50% full, or 100% full. When the portableelectronic device 306 receives data indicating that the memory device has reached a certain level of capacity, such as being totally full, the portableelectronic device 306 may begin to download saved data from thefile 700 on the memory device of thesport ball 106. In this way, communications between the portableelectronic device 306 and thesport ball 106 can be reduced to only the most essential communications, and data storage on the memory of thesport ball 106 can be managed. - In another embodiment, the
sport ball 106 may broadcast the status of its memory capacity without prompting for such information by the portableelectronic device 306. In an alternate embodiment, the portableelectronic device 306 may constantly download saved data from thefile 700 on the memory device of thesport ball 106. -
FIG. 25 is an exemplary GUI window that may be provided by the kick it module that provides a visual display to the individual 10 giving them feedback about the motion characteristics of thesoccer ball 106 during their kick. The exemplary GUI includes astatistical display bar 606 that may provide, for example, information on the maximum speed of thesoccer ball 106 during the post-kick flight or information on the maximum spin rate of thesoccer ball 106 during the post-kick flight. In some embodiments, thestatistical display bar 606 may also provide an indication of which foot 12 the individual 10 kicked thesoccer ball 106 with, as well as an indication of whether the individual 10 has designated the kick as a “favorite” kick. - The exemplary GUI of
FIG. 25 also includes avideo element 610. Theexemplary video element 610 shown is an animation that represents the flight path of the kickedsoccer ball 106 in three dimension, set upon the background of a representation of a soccer goal. In some embodiments the animation may start automatically, while in other embodiments the individual 10 must provide an input to the portableelectronic device 306 to request that the video play. In one embodiment, the perspective of the animated flight path may change such that the individual's 10 perspective may appear to rotate around the animated flight path to provide a better perspective on the flight path. In another embodiment the individual 10 may be presented with aselection icon 604 allowing the individual 10 to choose different animated views of the kick and fight path such as, for example, a downfield view, an angled view, or a side view. The particular flight path shown and animated may be based partially or entirely on the determined motion characteristics of thesoccer ball 106, such that the flight animated flight path is a realistic approximation of the actual flight path of the kickedsoccer ball 106. - Other visual displays giving feedback about the motion characteristics of the
soccer ball 106 during their kick may also be provided to the individual 10. In one embodiment, as shown inFIG. 25 , aswipe element 608 may indicate to the individual 10 that swiping their finger across the display screen may lead to other pages that display additional feedback. In other embodiments, buttons, switches, links, or other elements may be substituted for aswipe element 608. -
FIG. 26 is an exemplary GUI window that may be provided by the kick it module that provides one such other visual display—a ball strike display. For example, the exemplary GUI window ofFIG. 26 could be displayed to the individual 10 after the individual 10 swiped the display of the exemplary GUI window ofFIG. 25 to transition from the display of flight path feedback to the display ofFIG. 26 . -
FIG. 26 provides information on point ofimpact 150 data. Such data may be obtained, for example, according to aregression process 460 analysis as described above with respect toFIGS. 16-21 . As noted above, a relationship exists between the location of the point ofimpact 150 between an individual's 10foot 12 and asoccer ball 106 and motion characteristics of thesoccer ball 106 during and after it is kicked. The exemplary GUI displayFIG. 26 illustrates a point ofimpact icon 612 overlaid on top of aball icon 602, where the point ofimpact icon 612 is representative of the calculated point ofimpact 150 derived from theregression process 460 analysis as described above with respect toFIGS. 16-21 . In other words, the point ofimpact icon 612 displayed via portableelectronic device 306 corresponds to the calculated point ofimpact 150 that represents the location on the surface of thesoccer ball 106 that approximately coincides with the center of the area of thefoot 12 in contact with thesoccer ball 106. - Accordingly, the methods previously described for analyzing the relationship between the location of the point of
impact 150 between an individual's 10foot 12 and asoccer ball 106 and motion characteristics of thesoccer ball 106 during and after it is kicked can be used to generate feedback to the individual 10 via the portableelectronic device 306, such as visually illustrating the location of a point ofimpact icon 612 overlaid on top of aball icon 602, as shown inFIG. 26 . The point ofimpact icon 612 shown inFIG. 26 includes a circular dot with a series of animated rings that may visually “pulse” to help draw attention to the location of the point ofimpact icon 612. This particular point ofimpact icon 612 appears below and to the right of the center of thesoccer ball 106, as viewed from a front perspective. - The exemplary GUI window of
FIG. 26 also includes the samestatistical display bar 606 shown inFIG. 25 that provides information on the maximum speed of thesoccer ball 106 during the post-kick flight, information on the maximum spin rate of thesoccer ball 106 during the post-kick flight, an indication of which foot 12 the individual 10 kicked thesoccer ball 106 with, as well as an indication of whether the individual 10 has designated the kick as a “favorite” kick. The exemplary GUI window ofFIG. 26 additionally includes thesame swipe element 608 shown inFIG. 25 that may indicate to the individual 10 that swiping their finger across the display screen may lead to other pages that display additional feedback. Again, other embodiments, buttons, switches, links, or other elements may be substituted for aswipe element 608. - In one embodiment of the present invention, the
motion monitoring system 100 application running on the portableelectronic device 306 may log and display multiple point ofimpact icons 612 corresponding to multiple points ofimpact 150 between an individual's 10foot 12 and asoccer ball 106 during multiple kicks. Such a display is illustrated inFIG. 27 . The displayed kicks may be consecutive kicks from a single session, or may be from other periods of time. In an embodiment, the ball strike display may be limited to generating a display corresponding to a certain number of most recent points ofimpact 150, such as the last five points ofimpact 150, or the last ten points ofimpact 150. In one embodiment, multiple point ofimpact icons 612 corresponding to each point ofimpact 150 are displayed as a heatmap overlay over asingle ball icon 602. Point ofimpact icons 612 associated with earlier kicks may be displayed as somewhat transparent, becoming progressively more transparent over time until they are removed. In addition, or alternatively, point ofimpact icons 612 associated with more recent kicks may be larger, getting progressively smaller over time until they are removed. In some embodiments, theball icon 102 is lightened in the ball strike view ofFIG. 26 so as to reduce contrast so that the point ofimpact icon 612 heatmap is easier to see. - At any time when viewing their results, the individual 10 may be presented with a prompt to tap the
ball icon 602—or to tap a separate icon such as an icon including an message to “kick again” as shown inFIG. 27 —in order to repeat thesoccer ball 106 kicking and tracking sequence. In this way, a series of kicks may be tracked and feedback may be provided as described above. - Other visual displays giving feedback about the motion characteristics of the
soccer ball 106 during their kick may also be provided to the individual 10. In one embodiment, as shown inFIG. 27 , aswipe element 608 may indicate to the individual 10 that swiping their finger across the display screen may lead to other pages that display additional feedback. Again, in other embodiments, buttons, switches, links, or other elements may be substituted for aswipe element 608. -
FIG. 28 is an exemplary GUI window that may be provided by the kick it module that provides one such other visual display—a spin display. For example, the exemplary GUI window ofFIG. 28 could be displayed to the individual 10 after the individual 10 swiped the display of the exemplary GUI window ofFIG. 25, 26 , or 27 to transition from the display of flight path or ball strike feedback to the spin display ofFIG. 28 . -
FIG. 28 provides information on ball spin data. Such data may be obtained, for example, according to analysis as described above with respect toFIGS. 9-14 using asport ball 106 having asensor module 102. The exemplary GUI window ofFIG. 28 also includes the samestatistical display bar 606 shown inFIG. 25 and other figures that provides information on the maximum speed of thesoccer ball 106 during the post-kick flight, information on the maximum spin rate of thesoccer ball 106 during the post-kick flight, an indication of which foot 12 the individual 10 kicked thesoccer ball 106 with, as well as an indication of whether the individual 10 has designated the kick as a “favorite” kick. The exemplary GUI window ofFIG. 26 additionally includes thesame swipe element 608 shown inFIG. 25 and other figures that may indicate to the individual 10 that swiping their finger across the display screen may lead to other pages that display additional feedback. Again, other embodiments, buttons, switches, links, or other elements may be substituted for aswipe element 608. - The exemplary GUI window of
FIG. 28 features aball icon 602. In one embodiment, thisball icon 602 may be animated or otherwise depicted to represent the actual spin rate and spin axis of thesoccer ball 106 during flight. For example, theball icon 602 illustrated inFIG. 28 appears to be spinning rapidly with topspin. In embodiments of the present invention, theball icon 602 may depict ball spin by way of animation, by way of a stationary image with indicia (e.g. arrows) to indicate a direction of spin, or by simply providing a numerical spin rate value, such as three hundred revolutions per minute. In some embodiments, as depicted inFIG. 28 , theball icon 602 may include a ringed border demarcating various zones such as topspin, backspin, or various “bend” zones. The bend zones may correspond to kicks that have sidespin alone or some degree of sidespin coupled with topspin or backspin. - In one embodiment of the preset invention, the visually depicted spin rate of an animated
spinning ball icon 602 may be equal to the calculated spin rate of thesoccer ball 106 as determined by thesensor module 102. For example, if the calculated spin rate of thesoccer ball 106 is three hundred revolutions per minute, the visually depicted spin rate of an animatedspinning ball icon 602 may three hundred revolutions per minute. In another embodiment of the present invention, the visually depicted spin rate of an animatedspinning ball icon 602 may be proportional to, but not equal to, the calculated spin rate of thesoccer ball 106 as determined by thesensor module 102. For example, if the calculated spin rate of thesoccer ball 106 is three hundred revolutions per minute, the visually depicted spin rate of an animatedspinning ball icon 602 may half of that spin rate—or one hundred and fifty revolutions per minute. In still other embodiments, the visually depicted spin rate of an animatedspinning ball icon 602 may not be correlated to the calculated spin rate of thesoccer ball 106. - In one embodiment where the portable
electronic device 306 utilizes a touch screen display, the individual 10 may tap the animatedspinning ball icon 602 to stop the spinning animation. In other embodiments, other forms of user input may be used to stop the spinning animation. When the spinning animation is stopped, in some embodiments, a point ofimpact icon 612 is overlaid on top of a nowstatic ball icon 602, where the point ofimpact icon 612 is representative of the calculated point ofimpact 150, as described above with respect toFIGS. 26 and 27 . In other embodiments, the point ofimpact icon 612 may be displayed over a still spinning animatedspinning ball icon 602, or aspinning ball icon 602 that has reduced its rate of spinning to better allow for viewing of the point ofimpact icon 612. In embodiments where the spinning animation is stopped by the individual 10 tapping theball icon 602, the individual 10 re-tapping the stopped icon may restart the spinning. - In this way, the ball flight path, ball strike, and ball spin visual display and feedback features illustrated in
FIGS. 25-28 can provide an individual 10 with useful and visually interesting feedback on the motion characteristics of their kicks of asport ball 106, such as asoccer ball 106. As previously noted, in some embodiments, thestatistical display bar 606 may provide an indication of whether the individual 10 has designated a particular kick as a “favorite” kick. The individual 10 may designate a kick as a favorite kick after reviewing their feedback while viewing a display such as those ofFIGS. 25-28 by providing a user input to portableelectronic device 306, such as by tapping a “favorite” icon. Themotion monitoring system 100 will then save a record of the kick being a favorite kick of the individual 10 in a memory device in one or more of the portableelectronic device 306, or at aremote server 302. - Embodiments of the present invention may also provide for live video recording of kicks that can provide additional feedback to the individual 10 on their kick.
FIG. 29 is an exemplary GUI window that may be provided by the kick it module that includes avideo element 610 icon to enable this functionality. In one embodiment, thevideo element 610 icon may only be displayed if the individual's 10 portableelectronic device 306 includes or is paired to a suitable video recording component, such as a digital video camera of the portableelectronic device 306.FIG. 29 also shows a prompt to tap theball icon 602 when they are ready to monitor a kick using themotion monitoring system 100, similar to the display depicted inFIG. 24 . If not previously selected, the individual 10 may activate aselection video element 610 icon for indicating a desire to use the video recording features. When theball icon 602 is tapped indicating a desire to proceed with a kick with the video features enabled, in one embodiment, the GUI background may appear with a view of a live video feed from the video camera of the portableelectronic device 306. -
FIG. 30 is an exemplary GUI window showing a view of a live video feed from the video camera of the portableelectronic device 306. In this example, the individual 10 has oriented the portableelectronic device 306 and its camera such that thesoccer ball 106 and an intended soccer goal are visible, including the individual's 10 likely approach route to thesoccer ball 106 and the soccer ball's 106 likely flight path area. An individual 10 may achieve this portableelectronic device 306 and camera orientation by, for example, having a friend or coach hold and position the portableelectronic device 306 or by setting the portableelectronic device 306 on the ground or other surface, with or without a stand or other support. - As previously described, in response to receiving an indication that the individual 10 is ready to monitor a kick (e.g. the individual 10 taps the ball icon 602), the portable
electronic device 306 may communicate with thesoccer ball 106 having asensor module 102 to notify thesoccer ball 106 to expect a kick. In another embodiment, thesoccer ball 106 may send a return signal to the portableelectronic device 306 to indicate that thesoccer ball 106 is ready to be kicked. As this data communicating process is occurring, in one embodiment, the portableelectronic device 306 may continue to present a GUI background with a view of a live video feed from the video camera of the portableelectronic device 306, possibly with status updates displayed overlaying the live video feed informing the individual 10 of the communication status and finally informing the individual 10 that they may kick thesoccer ball 106. - When the
soccer ball 106 is kicked, thesensor module 102 is capable of recording movement date associated with the kick, as described above with respect toFIGS. 8-21 . Thesoccer ball 106 having thesensor module 102, alone or in combination with the portableelectronic device 306, may be capable of determining motion characteristics of thesoccer ball 106 including ball speed, ball spin rate, ball spin axis, and ball launch angle, as previously described. In another embodiment, the video camera of the portableelectronic device 306 may record a video that captures a result of the impact of the sport ball by the individual during the course of an athletic activity, and use video motion analysis techniques to determine motion characteristics of thesoccer ball 106 including ball speed, ball spin rate, ball spin axis, and ball launch angle. In other embodiments, these motion characteristics of thesoccer ball 106 may be determined using bothsensor module 102 and video motion analysis techniques to increase accuracy. - When the video features of the present invention are enabled,
FIG. 31 is an exemplary GUI window that may be provided by the kick it module that provides a visual display to the individual 10 giving them feedback about the motion characteristics of thesoccer ball 106 during their kick, including video feedback. - As with previous exemplary GUIs discussed, the exemplary GUI of
FIG. 31 includes astatistical display bar 606 that may provide, for example, information on the maximum speed of thesoccer ball 106 during the post-kick flight or information on the maximum spin rate of thesoccer ball 106 during the post-kick flight. In some embodiments, thestatistical display bar 606 may also provide an indication of which foot 12 the individual 10 kicked thesoccer ball 106 with, as well as an indication of whether the individual 10 has designated the kick as a “favorite” kick. The exemplary GUI ofFIG. 31 also includes avideo element 610. - In one embodiment, video recording is enabled as soon as the individual 10 enters an input to the portable
electronic device 306 indicating that video recording is desired. In another embodiment, however, nothing is recorded by themotion monitoring system 100 until thesoccer ball 106 is kicked, or until another event has occurred. - In another embodiment of the present invention, the portable
electronic device 306 may process video data in a temporary buffer memory and later store video data in a more permanent memory file only after it is determined that the memory device of thesport ball 306 has reached a certain level of capacity. This video data processing procedure may be similar to the system described for managing acceleration data storage on the memory of thesport ball 106 using a circular buffer previously described above. - After the kick, the video may be auto-clipped at, for example, two seconds prior to the memory device of the
sport ball 306 reaching a certain level of capacity, such as 10% full, and then clipped again, for example, six seconds later, for a final eight-second video. This approach captures the duration of a typical kick and generates a video that is reasonably sized for sharing via a variety of social media or other communication channels. In another embodiment, if the individual 10 proceeds to conduct and take video recordings of additional kicks, the software application may auto-clip the video again once additional kicks are initiated to create an even shorter clip to further save on memory space. - In an embodiment, the video may initially display as a still image on the display screen, prompting the individual 10 to tap the screen. Simple text overlays may be provided to explain the desired user interface interaction, and may fade out once the screen is tapped. In an embodiment, when the screen is tapped the video will advance one frame either forwards or backwards depending on the tap location. For example, the right half of the screen may advance the video forward, while the left half of the screen may advance the video backward. Enabling the individual 10 to advance the video one frame at a time in this manner may aid in carefully examining the individual's 10 form during a kick as well as the flight path and characteristic of the
soccer ball 106 during the kick. In this way, the individual 10 is provided with both recorded video feedback as well as the calculated feedback described above. - The embodiment depicted in
FIG. 31 includes astatistical display bar 606 that may provide, for example, information on the maximum speed of thesoccer ball 106 during the post-kick flight or information on the maximum spin rate of thesoccer ball 106 during the post-kick flight at the top of the display. In some embodiments, instead of always displaying maximum speed and maximum spin rate, thestatistical display bar 606 may display an instantaneous speed and spin rate that are correlated with the displayed video feedback. For example, themotion monitoring system 100 software application may correlate speed, spin rate, and other motion data with the displayed video feedback based on the time associated with the motion data and each individual video frame. In this way, as the individual 10 advances the video frame-by-frame either forwards or backwards in slow motion or at a faster pace, thestatistical display bar 606 may change the value for the speed, spin rate, and other motion data displayed to match what was determined for the point in time corresponding to the current video image being shown. - While viewing the video display screen, a
swipe element 608 may indicate to the individual 10 that swiping their finger across the display screen may lead to other pages that display additional feedback, such as the exemplary pages shown inFIGS. 25-28 . - As noted above with respect to
FIG. 22 , the individual 10 may navigate to amenu 600 GUI that includes several icons or indicia corresponding to, for example, kick it, get better, challenges, and record book modules, as well as icons or indicia corresponding to settings or help features. The individual 10 may cause different GUI pages to be provided by different modules by selecting their corresponding icons using user input controls. Additional icons corresponding to sub-modules or program wizards associated with a particular module may pop up or otherwise be displayed to the individual 10 if the individual 10 selects, swipes, or hovers over a module icon with a cursor. -
FIG. 32 is an exemplary GUI window depicting a get better menu GUI that includes several icons or indicia corresponding to several different sub-modules offering training via several different drills forspecific sport ball 106 performance skills, such asparticular soccer ball 106 kicking skills. Sub-modules may exist for drills to enhance the individual's 10 general form in kicking asoccer ball 106, their ability to generate a more powerful kick, their ability to bend asoccer ball 106 with a kick (i.e. impart desired relatively high level of spin), and their ability to kick a knuckle ball (i.e. kick a ball with little or no spin). In one embodiment, specific ball mastery, ball striking, striking with power, around the wall, over the wall, and knuckle ball modules are offered. - When a ball mastery sub-module is selected and executed by the portable
electronic device 306 for the individual 10, a display of the portableelectronic device 306 may provide the individual 10 with a menu of training videos to choose from. The training videos may provide the individual 10 with instructions and examples of how to executegeneral soccer ball 106 handling movements. Videos, still images, audio, and/or text may be provided to the individual 10. For example, in one embodiment the individual 10 may be presented with instructions for executing toe taps and outside rolls. A video of toe taps and outside rolls may be provided. Before, after, or during the video, audio or text may inform the individual 10 that they should start slowly, be on their toes and add a little hop when they roll outside, and that both of their feet should be working together, using both the inside and soles of the feet. In some embodiments, thesoccer ball 106 having asensor module 102 may be used to monitor the individual's 10 execution of the toe taps and outside roll maneuver and provide feedback on the performance. - In one embodiment of the present invention, the videos and/or still images may provide the individual 10 with instructions and examples of how to execute
general soccer ball 106 handling movements that provide guidance, in part, based onexterior markings 202 of thesoccer ball 106, such as those briefly noted above with respect toFIGS. 5 and 16 . In addition toexterior markings 202 being useful to indicate the optimum orientation ofsoccer ball 106 for charging, suchexterior markings 202 may additionally or alternatively be useful to help the individual 10 properly orient theirsoccer ball 106 prior to a kick and to serve as landmarks for their intended point ofimpact 150 with thesoccer ball 106. For example, in the exemplary embodiment ofFIG. 16 , the illustrated point ofimpact 150 is vertically aligned with the linearexterior markings 202 on the front face and center of thesoccer ball 106. In an embodiment, instructions and examples of how to kick asoccer ball 106 may incorporate references to locations of one or moreexterior markings 202, such as a videos and/or still images showing the individual 10 that they should attempt to kick thesoccer ball 106 with theirfoot 12 so that the point ofimpact 150 is vertically aligned with the central linear exterior marking 202. - In another embodiment, when a ball striking sub-module is selected and executed by the portable
electronic device 306 for the individual 10, a display of the portableelectronic device 306 may provide the individual 10 with instructions ongeneral soccer ball 106 kick striking tips. Videos, still images, audio, and/or text may be provided to the individual 10. For example, in one embodiment the individual 10 may be presented with instructions forgeneral soccer ball 106 kick striking. A video ofgeneral soccer ball 106 kick striking may be provided. Before, after, or during the video, audio or text may inform the individual 10 that they should plant theirfoot 12, strike thesoccer ball 106, and follow through. For example, the individual 10 may be instructed to “land on your plant foot just behind the ball with it pointed toward the target, and allow enough space between your plant foot and the ball to ensure full extension of your kicking foot.” An accompanying video, animation, or still image may be provided for guidance. The individual 10 may also be instructed to “keep your foot pointed down with your ankle locked as you swing your leg to strike, and drive the top of your boot squarely into the center of the ball,” and to “make sure you focus on the connection with ball before lifting your head and going into your follow through, and keep your follow through relatively low for this type of strike.” Again, an accompanying video, animation, or still image may be provided for guidance, and they may incorporate references to locations of one or moreexterior markings 202 of thesoccer ball 106. At this point, the individual 10 may then be tested on their comprehension and mastery of this skill. - In response to receiving an indication that the individual 10 is ready to monitor a kick (e.g. the individual 10 taps the ball icon 602) to test their
general soccer ball 106 kick striking skills via the ball strike sub-module, the portableelectronic device 306 may communicate with thesoccer ball 106 having asensor module 102 to notify thesoccer ball 106 to expect a kick, as previously described. When thesoccer ball 106 is kicked, thesensor module 102 is capable of recording movement date associated with the kick, as described above with respect toFIGS. 8-21 . Thesoccer ball 106 having thesensor module 102, alone or in combination with the portableelectronic device 306, may be capable of determining motion characteristics of thesoccer ball 106 including ball speed, ball spin rate, ball spin axis, and ball launch angle, as previously described. - When the individual 10 is testing their
general soccer ball 106 kick striking skills via the ball strike sub-module,FIG. 33 is an exemplary GUI window that may be provided showing a visual display to the individual 10 giving them feedback about the motion characteristics of thesoccer ball 106 during their kick, including feedback on whether they were properly striking thesoccer ball 106, as evidenced in part by their point ofimpact 150. As with previous exemplary GUIs discussed, the exemplary GUI ofFIG. 33 includes astatistical display bar 606 that may provide, for example, information on the maximum speed of thesoccer ball 106 during the post-kick flight or information on the maximum spin rate of thesoccer ball 106 during the post-kick flight. The exemplary GUI ofFIG. 33 also illustrates a point ofimpact icon 612 overlaid on top of aball icon 602, where the point ofimpact icon 612 is representative of the calculated point ofimpact 150 derived from theregression process 460 analysis as described above with respect toFIGS. 16-21 . In other words, the point ofimpact icon 612 displayed via portableelectronic device 306 corresponds to the calculated point ofimpact 150 that represents the location on the surface of thesoccer ball 106 that approximately coincides with the center of the area of thefoot 12 in contact withsoccer ball 106. In addition, in some embodiments, a desiredstrike zone 140 and/or point ofimpact 150 corresponding the preferredstrike zone 140 and/or point ofimpact 150 based on thegeneral soccer ball 106 kick striking tips previously provided may also be displayed. - Accordingly, the methods previously described for analyzing the relationship between the location of the point of
impact 150 between an individual's 10foot 12 and asoccer ball 106 and motion characteristics of thesoccer ball 106 during and after it is kicked can be used to generate feedback to the individual 10 via the portableelectronic device 306, such as visually illustrating the location of a point ofimpact icon 612 overlaid on top of aball icon 602. In this way, the individual 10 can visually see how they need to adjust their kick mechanics to achieve a better kick. InFIG. 33 , the individual's 10 recorded point ofimpact icon 612 appears just below and to the right of the preferred point ofimpact 150 based on thegeneral soccer ball 106 kick striking tips previously provided may also be displayed. In one embodiment, themotion monitoring system 100 application may provide feedback to the individual 10 that “your kick is a bit low and to the right of the strike zone, you should adjust your kick to strike closer to the center of the ball.” - In another embodiment, when a striking with power sub-module is selected and executed by the portable
electronic device 306 for the individual 10, a display of the portableelectronic device 306 may provide the individual 10 with instructions ongeneral soccer ball 106 kick striking tips to enhance the power (i.e. speed) of a kick. Execution of this sub-module is in many ways similar to the execution of thesoccer ball 106 strike module just described. The individual 10 may be provided with videos, animations, audio and/or text explaining how they should plant theirfoot 12, strike thesoccer ball 106, follow through, and make any other necessary adjustments to generate more power (i.e. speed) for their kicks. - GUIs displayed to provide feedback to the individual 10 for the striking with power sub-module may be similar to those previously described with respect to
FIGS. 25-28 and 33 . In addition, when the individual 10 is testing their generalpower soccer ball 106 kick striking skills via the striking with power sub-module,FIG. 34 is an exemplary GUI window that may be provided showing a visual display to the individual 10 giving them feedback about the power characteristics of thesoccer ball 106 during their kick, including feedback on the speed of thesoccer ball 106. In addition to thestatistical display bar 606 that may provide, for example, information on the maximum speed of thesoccer ball 106 during the post-kick flight or information on the maximum spin rate of thesoccer ball 106 during the post-kick flight at the top of the window, a differentstatistical display area 606 focused on speed may also be presented. In an embodiment, thisstatistical display area 606 may include a speed number animation that starts with a display of zero and rapidly builds up to the result. The last five speed readings for recent kicks may also be displayed immediately below. For example, the exemplary embodiment ofFIG. 34 , an animated display would cycle up from zero miles per hour to a display of 51 miles per hour, and recent kick speeds of 53 and 49 miles per hour would be displayed below this. - In another embodiment, when a bend around the wall sub-module is selected and executed by the portable
electronic device 306 for the individual 10, a display of the portableelectronic device 306 may provide the individual 10 with instructions onsoccer ball 106 kick striking tips to be able to bend a kick (i.e. apply targeted spin) around a defensive wall (i.e. a line of defenders forming a barrier against a free kick taken near the penalty area). Execution of this sub-module is in many ways similar to the execution of the ball strike and striking with power sub-modules just described. The individual 10 may be provided with videos, animations, audio and/or text explaining how they should plant theirfoot 12, strike thesoccer ball 106, follow through, and make any other necessary adjustments to generate bend (i.e. targeted spin) for their kicks. Again, an accompanying video, animation, or still image may be provided for guidance, and they may incorporate references to locations of one or moreexterior markings 202 of thesoccer ball 106. -
FIG. 35 is an exemplary GUI window that may be provided showing a visual display to the individual 10 giving them video, animated, and/or still image instructions on how generate bend (i.e. targeted spin) for their kicks. For example, the individual 10 may be instructed to “approach the ball from a 45 degree angle” and to “aim to stroke the ball low with your heel close to the turf and lock your ankle throughout the strike.” The video, animated, and/or still images, such as the exemplary ones shown inFIG. 35 , may further aid the individual 10 in understanding the mechanics needed to achieve the desired outcome. In an embodiment, videos, animations, and/or still images may further be provided illustration what a successful kick around a wall (i.e. around a line of defenders forming a barrier against a free kick taken near the penalty area) would look like. Again, an accompanying video, animation, or still image may be provided for guidance, and they may incorporate references to locations of one or moreexterior markings 202 of thesoccer ball 106. As shown inFIG. 35 , moreexterior markings 202 are visible to the individual 10 in the GUI display and can therefore be used for additional guidance landmarks. - Other GUIs displayed to provide feedback to the individual 10 for the bend around the wall sub-module may be similar to those previously described with respect to
FIGS. 25-28 and 33 . In other words, feedback may be given to the individual 10 regarding the speed, spin, spin axis, launch angle, flight path, and/or point ofimpact 150 for their kicks. - In another embodiment, when a bend over the wall sub-module is selected and executed by the portable
electronic device 306 for the individual 10, display of the portableelectronic device 306 may provide the individual 10 with GUIs and feedback very similar to those provided for the bend around the wall sub-module. In an embodiment, the primary difference is in the coaching related to how the individual 10 should plant theirfoot 12, strike thesoccer ball 106, follow through, and make any other necessary adjustments to generate bend (i.e. targeted spin) for their kicks to go over a wall as opposed to around a wall. For example, the individual 10 may be instructed to “approach the ball from a 45 degree angle” and to “aim to stroke the ball low with your heel close to the turf and lock your ankle in an upward motion.” - In another embodiment, when a knuckle ball sub-module is selected and executed by the portable
electronic device 306 for the individual 10, display of the portableelectronic device 306 may provide the individual 10 with GUIs and feedback similar to those provided for the bend around the wall and bend over the wall sub-modules. In an embodiment, the primary difference is in the coaching related to how the individual 10 should plant theirfoot 12, strike thesoccer ball 106, follow through, and make any other necessary adjustments to generate a knuckle ball (i.e. kick asoccer ball 106 with little or no spin). For example, the individual 10 may be instructed to “make contact with the ball using the ankle joint center part of your foot looking to hit the ball in the middle to take the bend off” As with previously described embodiments, suitable videos, animations, and/or still images may further be provided illustration what a successful knuckle ball kick would look like. Again, an accompanying video, animation, or still image may be provided for guidance, and they may incorporate references to locations of one or moreexterior markings 202 of thesoccer ball 106. - GUIs displayed to provide feedback to the individual 10 for the knuckle ball sub-module may be similar to those previously described with respect to
FIGS. 25-28 and 33 . In addition, when the individual 10 is testing their knuckle ball kick striking skills via the knuckle ball sub-module,FIG. 36 is an exemplary GUI window that may be provided showing a visual display to the individual 10 giving them feedback about the spin characteristics of thesoccer ball 106 during their kick. In addition to thestatistical display bar 606 that may provide, for example, information on the maximum speed of thesoccer ball 106 during the post-kick flight or information on the maximum spin rate of thesoccer ball 106 during the post-kick flight at the top of the window, a differentstatistical display area 606 focused on speed may also be presented. In an embodiment, thisstatistical display area 606 including aball icon 102 may be provided. - As shown in
FIG. 36 , a series of concentric circles in a “bull's-eye” style configuration may provide several spin ranges, with the inner most circle being a relatively high spin range (e.g. over 200 revolutions per minute) and the outer most circle being a relatively low spin range (e.g. 0 to 20 revolutions per minute). For a kick registering a relatively high spin rate (e.g. 300 rpm), aball icon 102 may appear in the center of the bull's-eye with the rate of 300 rpm shown. But as shown inFIG. 36 , for a kick registering a relatively low spin rate (e.g. 12 rpm), a series ofball icons 102 may be illustrated as moving outward from the center of the bull's-eye toward the outer low-spin ring, this giving the impression of asoccer ball 106 moving without much spin—in other words a knuckle ball. In this way, the individual 10 is provided with additional visual feedback on how they are progressing to meeting their goal of kicking a knuckle ball in accordance with the guidelines of the knuckle ball sub-module. - As noted above with respect to
FIG. 22 , the individual 10 may navigate to amenu 600 GUI that includes several icons or indicia corresponding to, for example, kick it, get better, challenges, and record book modules, as well as icons or indicia corresponding to settings or help features. The individual 10 may cause different GUI pages to be provided by different modules by selecting their corresponding icons using user input controls. Additional icons corresponding to sub-modules or program wizards associated with a particular module may pop up or otherwise be displayed to the individual 10 if the individual 10 selects, swipes, or hovers over a module icon with a cursor. -
FIG. 37 is an exemplary GUI window depicting a challenges menu GUI that includes several icons or indicia corresponding to several different sub-modules offering additional ways for an individual 10 to further train or test theirsoccer ball 106 kicking skills. Sub-modules may exist for drills to improve or to test the individual's 10 ability to control their kick power (i.e. speed), control the bend of their kick (i.e. spin), or to mimic the power, bend, flight trajectory, or other characteristics of a sample kick from a professional soccer player. In one embodiment, specific power challenge, free kick challenge, and pro challenge modules are offered. - When a power challenge sub-module is selected and executed by the portable
electronic device 306 for the individual 10, a display of the portableelectronic device 306 may provide the individual 10 with feedback on their control their kick power (i.e. speed), such as via the exemplary GUI windows ofFIGS. 38-40 . -
FIG. 38 is an exemplary GUI window illustrating features of the power challenge sub-module. Initially, when a power challenge sub-module is selected and executed by the portableelectronic device 306 for the individual 10, display of the portableelectronic device 306 may provide the individual 10 with GUIs and feedback similar to those described above. As with previously described embodiments, suitable videos, animations, and/or still images may be provided. - In on embodiment, a
selection icon 604 in the form of a range selector may be presented to allow the individual 10 to set a desired kick speed range. For example, kick speed ranges may be set to have ranges of five, ten, or fifteen miles per hour. In the embodiment illustrated inFIG. 38 , a ten mile per hour range has been selected, meaning that the individual's 10 goal will be to kick thesoccer ball 106 at a speed that falls within a ten mile per hour range—here, 45 to 55 miles per hour.FIG. 38 also depicts arange wheel 614 that visually depicts the selected range of target kick speeds. In an embodiment, after initially selecting a speed range via theselection icon 604, the individual 10 can adjust the range by a user input such as a touch screen interface. For example, the individual 10 could rotate therange wheel 614 such that the ten mile per hour range covers a different range of speeds that are higher or lower that the initially presented speeds. In another embodiment, the individual 10 could expand or reduce the range by pinching or stretching over the portion of the range wheel icon that highlights the selected range. As shown in GIF. 38, the range wheel icon may also display the numerical range of the desired speeds in its center. - In some embodiments, the power challenge sub-module present the individual 10 with a solo challenge. In other embodiments, the power challenge sub-module can present the challenge to two or
more individuals 10 so that they can compete against each other. Aselection icon 604, such as that depicted inFIG. 38 , may allow the individual 10 to choose whether to engage in a solo challenge or whether to compete against two ormore individuals 10. - When the individual 10 is ready to begin the challenge, they may be presented with a prompt to tap a
ball icon 602 when they are ready to monitor a kick using themotion monitoring system 100, similar to the display depicted inFIG. 24 . In some embodiments, the GUIs displayed to provide feedback to the individual 10 for the power challenge may be similar to those previously described with respect toFIGS. 25-28 and 34 . In addition, when the individual 10 is engaged in a power challenge,FIG. 39 is an exemplary GUI window that may be provided showing a visual display to the individual 10 giving them feedback about their control of power (i.e. speed) characteristics of thesoccer ball 106 during their kicks. - The exemplary embodiment of
FIG. 39 depicts ascorecard 616 at the top of the display. The depicted embodiment is a challenge between two players,Player 1 andPlayer 2. Thescorecard 616 provides information on how many kicks each player has taken, and how many kicks each player is made. In one embodiment, themotion monitoring system 100 application running on the portableelectronic device 306 will prompt the players to switch off during the course of the challenge, withPlayer 1 kicking one ball, thenPlayer 2 kicking one ball, trading off until each player has kicked a maximum number of balls, such as five each. - For each kick, in one embodiment, the application may display a
statistical display 606 overlaid on top of therange wheel 614, as shown inFIG. 39 . In this exemplary embodiment therange wheel 614 previously shown when setting up the challenge may be presented again, while an arm is displayed overlaid on top of the range wheel pointing to the speed value associated with the individual's 10 last kick. In the depicted embodiment, the last kick was 53 miles per hour, resulting in the numerical display of 53 miles per hour, as well as the display of a dial arm pointing to a value of 53 miles per hour, which falls inside of the predetermined speed challenge range of 45 to 55 miles per hour. Because such a kick would be a successful kick in the challenge, thescorecard 616 would be updated to reflect a successful kick for that individual 10. -
FIG. 40 is an exemplary GUI window illustrating an additional power challenge feedback display, which could also serve as a final summary display for the challenge. As shown in this figure, a power challenge for kicks in the range of 45-55 miles per hour between two players named Tom and Julio was completed. As shown by thescorecard 616, which has a different appearance than thescorecard 616 ofFIG. 39 , Tom successfully completed his first, third, fourth, and fifth kicks, but his second kick was only 34 miles per hour, which was under the goal range of 45-55 miles per hour. On the other hand, Julio only successfully completed his fourth and fifth kicks, with his first three kicks being only 34 miles per hour, which was under the goal range of 45-55 miles per hour. Accordingly, Tom is declared the winner of the two-player power challenge. - A power challenge conducted as a solo challenge with only one player would proceed similarly to the two-player challenge outlined above, except that the individual 10 could take all five of their shots in sequence without interruption from another player. In another embodiment, if a two-player challenge is tied at the end of the set amount of kicks (e.g. five kicks each), the challenge may proceed to “sudden death” rounds where the players would trade off one kick at a time until one player failed to meet their goal in a round where the other player did meet their power goal.
- When a free kick challenge sub-module is selected and executed by the portable
electronic device 306 for the individual 10, a display of the portableelectronic device 306 may provide the individual 10 with feedback on their control the bend of their kick (i.e. spin), such as via the exemplary GUI windows ofFIGS. 41-43 . -
FIG. 41 is an exemplary GUI window illustrating features of the free kick challenge sub-module. Initially, when a free kick challenge sub-module is selected and executed by the portableelectronic device 306 for the individual 10, display of the portableelectronic device 306 may provide the individual 10 with GUIs and feedback similar to those described above. As with previously described embodiments, suitable videos, animations, and/or still images may be provided. - In one embodiment, a
wall icon 618 may be presented representing one or more defenders arranged in a “wall” formation to oppose a player taking a free kick toward a goal. As shown inFIG. 41 , thewall icon 618 may numerically indicate the number of defenders making up the wall and may further graphically illustrate each wall defender. In some embodiments, the individual 10 may increase or decrease the number of wall defenders by entering an input into the portableelectronic device 306, which will change the numerical indication of the number of wall defenders as well as the graphical illustration of the wall defenders. -
FIG. 41 also illustrates aselection icon 604 in the form of a goal distance selector that may be presented to allow the individual 10 to set a desired kick distance (i.e. distance from the goal). For example,selection icon 604 may allow the individual 10 to increase the distance to the goal in increments of five yards. The exemplary embodiment ofFIG. 41 also includes aselection icon 604 for aligning the wall defenders with the left post of the goal or the right post of the goal. Increasing or decreasing the number of defenders, increasing or decreasing the distance to the goal, and switching the alignment of the wall defenders form the left to the right post will impact the nature of a kick that will successfully score a goal. In one embodiment, increasing the number of wall defenders will decrease the width of zone where a goal could be successfully kicked into the net, which may be illustrated in the GUI display by more wall defender images being added. Similarly, increasing the distance to the goal will effectively decrease the height of zone where a goal could be successfully kicked into the net, which may also be illustrated in the GUI display by a shortening of a rectangle representing the soccer goal. Switching the alignment of the wall defenders between the left or right post will require the individual 10 to be able to bend theirsoccer ball 106 in one way or another to clear the wall defenders but still make the goal. In some embodiment, as illustrated inFIG. 41 , a goalkeeper defender may also be illustrated and may partially block the goal. - In some embodiments, the free kick challenge sub-module may present the individual 10 with an solo challenge. In other embodiments, the free kick challenge sub-module can present the challenge to two or
more individuals 10 so that they can compete against each other. Aselection icon 604, such as that depicted inFIG. 41 , may allow the individual 10 to choose whether to engage in a solo challenge or whether to compete against two ormore individuals 10. - When the individual 10 is ready to begin the challenge, they may be presented with a prompt to tap a
ball icon 602 when they are ready to monitor a kick using themotion monitoring system 100, similar to the display depicted inFIG. 24 . In some embodiments, the GUIs displayed to provide feedback to the individual 10 for the free kick challenge may be similar to those previously described with respect toFIGS. 25-28 and 33 . In addition, when the individual 10 is engaged in a free kick challenge,FIG. 42 is an exemplary GUI window that may be provided showing a visual display to the individual 10 giving them feedback about their control of bend (i.e. spin) characteristics of thesoccer ball 106 during their kicks. - The exemplary embodiment of
FIG. 42 depicts ascorecard 616 at the top of the display, which is similar to the scorecard ofFIG. 39 . The depicted embodiment is a challenge between two players,Player 1 andPlayer 2. Thescorecard 616 provides information on how many kicks each player has taken, and how many kicks each player is made. In one embodiment, themotion monitoring system 100 application running on the portableelectronic device 306 will prompt the players to switch off during the course of the challenge, withPlayer 1 kicking one ball, thenPlayer 2 kicking one ball, trading off until each player has kicked a maximum number of balls, such as five each. - For each kick, in one embodiment, the application may display a kick flight path overlaid on top of the
wall icon 618, as shown inFIG. 42 . In this exemplary embodiment thewall icon 618 and accompanying goal background previously shown when setting up the challenge may be presented again, while a kick flight path is displayed overlaid on top of thewall icon 618 and accompanying goal background. In the depicted embodiment, the last kick hit the second member of the wall, resulting in a failure to score a goal. Because such a kick would be an unsuccessful kick in the challenge, thescorecard 616 would be updated to reflect an unsuccessful kick for that individual 10. -
FIG. 43 is an exemplary GUI window illustrating an additional free kick challenge feedback display, which could also serve as a final summary display for the challenge. As shown in this figure, a free kick challenge with two wall defenders lined up on the left goal post between two players named Tom and Julio was completed. As shown by thescorecard 616, Tom scored four goals by bendingsoccer balls 106 around the wall. On the other hand, Julio only successfully scored one goal. Accordingly, Tom is declared the winner of the two-player power challenge. Each of Tom's and Julio's successful goals are illustrated by flight path lines traveling unimpeded into the goal. Although failed goals are not illustrated inFIG. 43 , in some embodiment, failed goals such as those blocked by a wall defender or goalie may also be illustrated. - A free kick challenge conducted as a solo challenge with only one player would proceed similarly to the two-player challenge outlined above, except that the individual 10 could take all five of their shots in sequence without interruption from another player. In another embodiment, if a two-player challenge is tied at the end of the set amount of kicks (e.g. five kicks each), the challenge may proceed to “sudden death” rounds where the players would trade off one kick at a time until one player failed to meet make a goal in a round where the other player did make a goal.
- When a pro challenge sub-module is selected and executed by the portable
electronic device 306 for the individual 10, a display of the portableelectronic device 306 may provide the individual 10 with challenge the individual 10 to mimic the power, bend, flight trajectory, or other characteristics of a sample kick from a professional soccer player, such as via the exemplary GUI windows ofFIGS. 44 and 45 . -
FIG. 44 is an exemplary GUI window illustrating features of the pro challenge sub-module. Initially, when a pro challenge sub-module is selected and executed by the portableelectronic device 306 for the individual 10, display of the portableelectronic device 306 may provide the individual 10 with GUIs and feedback similar to those described above. As with previously described embodiments, suitable videos, animations, and/or still images may be provided. In particular, videos, animations, and/or still images of a professional soccer player executing a specific kick or other maneuver, along with accompanying written or audio explanation, may be provided. Again, an accompanying video, animation, or still image may be provided for guidance, and they may incorporate references to locations of one or moreexterior markings 202 of thesoccer ball 106. - As shown in
FIG. 41 , a series ofpro challenge icons 620 may be presented to the individual 10. Apro challenge icon 620 may include a starting location for asoccer ball 106 to be placed with respect to a goal, a target ball speed, a target ball spin rate, a target ball trajectory, and other suitable characteristics. For example, the firstpro challenge icon 620 ofFIG. 44 illustrates a challenge where the individual 10 is tasked with kicking asoccer ball 106 around forty-six miles per hours with about 120 revolutions per minute of spin over the top of a five person wall from just outside the middle of the penalty area. In some embodiments, aselection icon 604 may also be used to indicate whichfoot 12 the individual 10 is kicking with. Specific pro challenges may be associated with specific professional soccer players. In this case, videos, animations, and/or still images of the player may be shown to illustrate the kick, or written or audio explanation may be provided from the player. - In some embodiments, the pro challenge sub-module may present the individual 10 with a solo challenge. In other embodiments, the pro challenge sub-module can present the challenge to two or
more individuals 10 so that they can compete against each other. - When the individual 10 is ready to begin the pro challenge, they may be presented with a prompt to tap a
ball icon 602 when they are ready to monitor a kick using themotion monitoring system 100, similar to the display depicted inFIG. 24 . In some embodiments, the GUIs displayed to provide feedback to the individual 10 for the pro challenge may be similar to those previously described with respect toFIGS. 25-28 . In addition, when the individual 10 is engaged in a pro challenge,FIG. 45 is an exemplary GUI window that may be provided showing a visual display to the individual 10 giving them feedback about their ability to mimic the power, bend, flight trajectory, or other characteristics of a sample kick from a professional soccer player during their kicks. - The exemplary embodiment of
FIG. 45 provides a visual display to the individual 10 giving them feedback about the motion characteristics of thesoccer ball 106 during their kick, and how it compares to the professional's kick. The exemplary GUI includes astatistical display 606 that may provide, for example, information on the maximum speed of thesoccer ball 106 during the post-kick flight or information on the maximum spin rate of thesoccer ball 106 during the post-kick flight, as well as how these speed and spin numbers compare to any target numbers provided for the model professional kick. For example, in the illustrated embodiment, the targets for the professional model kick were forty-seven miles per hour and three hundred revolutions per minute, while the individual's 10 recorded kick was seventy-two miles per hour and thirty-six revolutions per minute. -
FIG. 45 further illustrates ascorecard 616, which awards the individual 10 anywhere from one to five stars based on how closely they matched the model professional kick. In the illustrated embodiment, the individual 10 was awarded three stars. - The exemplary GUI of
FIG. 25 also includes avideo element 610. Theexemplary video element 610 shown is an animation that represents the flight path of the kickedsoccer ball 106 in three dimension, set upon the background of a representation of a soccer goal, as well as a an animation that represents the flight path of the model professional kick. In some embodiments the animation may start automatically, while in other embodiments the individual 10 must provide an input to the portableelectronic device 306 to request that the video play.
